2006-01-25  Jeff Hobbs  <jeffh@ActiveState.com>

	*** Bump to TEA version 3.5 ***

	* tcl.m4: keep LD_SEARCH_FLAGS and CC_SEARCH_FLAGS synchronous
	with core tcl.m4 meaning.

................................................................................

2006-01-04  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: remove extraneous ' that causes bash 3.1 to choke

2005-12-19  Joe English  <jenglish@users.sourceforge.net>

	* tcl.m4 (TEA_PATH_TCLCONFIG &c): Look for tclConfig.sh &c 
	in ${libdir}, where they are installed by default [Patch #1377407].

2005-12-05  Don Porter  <dgp@users.sf.net>

	* tcl.m4 (TEA_PUBLIC_*_HEADERS):	Better support for finding
	header files for uninstalled Tcl and Tk.

................................................................................
	Make STLIB_LD use $LINKBIN -lib.

2005-01-25  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (Darwin): fixed bug with static build linking to dynamic
	library in /usr/lib etc instead of linking to static library earlier
	in search path. [Tcl Bug 956908]
	Removed obsolete references to Rhapsody. 
	
2004-12-29  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: Updates for VC7 compatibility, fixing CFLAGS and LDFLAGS
	options, using better default -O levels. [Bug 1092952, 1091967]

2004-12-29  Joe English  <jenglish@users.sourceforge.net>

................................................................................
	of gcc to ${CC}.

2002-10-15  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: move the CFLAGS definition from TEA_ENABLE_SHARED to
	TEA_MAKE_LIB because setting too early confuses other AC_* macros.
	Correct the HP-11 SHLIB_LD_LIBS setting.
	
	* tcl.m4: add the CFLAGS definition into TEA_ENABLE_SHARED and
	make it pick up the env CFLAGS at configure time.

2002-10-09  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: add --enable-symbols=mem option to enable TCL_MEM_DEBUG.
	Improved AIX 64-bit build support, allow it on AIX-4 as well.
................................................................................
	Add TK_BIN_DIR to paths to find wish in SC_PROG_WISH.
	These move towards making TEA much more independent of *Config.sh.

2002-03-19  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: corrected forgotten (UN)SHARED_LIB_SUFFIX and
	SHLIB_SUFFIX defines for Win.
	(SC_PATH_X): made this only do the check on unix platforms. 

2002-03-12  Jeff Hobbs  <jeffh@ActiveState.com>

	* README.txt: updated to reflect fewer files

2002-03-06  Jeff Hobbs  <jeffh@ActiveState.com>

................................................................................
	* installFile.tcl: Added updating of the modification time of
	  the target file whether we overwrote it or decided that it
	  hadn't changed.  This was necessary for us to be able to
	  determine whether or not a module install touched the file.

2001-03-08    Karl Lehenbauer <karl@procplace.com>

	* installFile.tcl: Added support for converting new-style (1.1+) 
	  Cygnus drive paths to Tcl-style.

2001-01-15    <brent.welch@interwoven.com>

	* tcl.m4: Added FreeBSD clause.

2013-03-12  Jan Nijtmans  <nijtmans@users.sf.net>

	* unix/tcl.m4: Patch by Andrew Shadura, providing better support for
	* three architectures they have in Debian.

2012-08-07  Stuart Cassoff  <stwo@users.sourceforge.net>

	* tcl.m4: Added "-DNDEBUG" to CFLAGS_DEFAULT
	when building with --disable-symbols.

2012-08-07  Stuart Cassoff  <stwo@users.sourceforge.net>

	* tcl.m4: [Bug 3555058]: Checkin [30736d63f0] broke
	CFLAGS_DEFAULT, LDFLAGS_DEFAULT

2012-08-07  Stuart Cassoff  <stwo@users.sourceforge.net>

	* tcl.m4: [Bug 3511806]: Checkin [30736d63f0] broke CFLAGS

2012-08-07  Jan Nijtmans  <nijtmans@users.sf.net>

	* tcl.m4: [Bug 3511806]: Checkin [30736d63f0] broke CFLAGS

2012-07-25  Jan Nijtmans  <nijtmans@users.sf.net>

	* tcl.m4: My previous commit (2012-04-03) broke the ActiveTcl
	build for AMD64, because of the quotes in "C:/<path>/AMD64/cl.exe".
	It turns out that the AC_TRY_COMPILE macro cannot handle that.

2012-07-22  Stuart Cassoff  <stwo@users.sourceforge.net>

	* tcl.m4: Tidy: consistency, spelling, phrasing, whitespace.
	No functional change.

2012-04-03  Jan Nijtmans  <nijtmans@users.sf.net>

	* tcl.m4: [Bug 3511806] Compiler checks too early
	This change allows to build the cygwin and mingw32 ports of
	Tcl/Tk extensions to build out-of-the-box using a native or
	cross-compiler, e.g. on Cygwin, Linux or Darwin.

2011-04-02  Jan Nijtmans  <nijtmans@users.sf.net>

	* install-sh: Fix issue with library stripping in install-sh
	 (backported from kevin_walzer's patch from Tcl 8.6 trunk)

2011-04-05  Andreas Kupries  <andreask@activestate.com>

	* tcl.m4: Applied patch by Jeff Lawson. Nicer error message when
	  tclConfig.sh was not found.

2010-12-15  Stuart Cassoff  <stwo@users.sourceforge.net>

	* install-sh: Upgrade to newer install-sh and use it.
	* tcl.m4:

2010-12-14  Stuart Cassoff  <stwo@users.sourceforge.net>

	* tcl.m4: Better building on OpenBSD.

2010-12-14  Jan Nijtmans  <nijtmans@users.sf.net>

	* tcl.m4: when using gcc, don't try to determine Win64 SDK

2010-12-12  Jan Nijtmans  <nijtmans@users.sf.net>

	* tcl.m4: Determine correctly a cross-compiler-windres

2010-11-23  Jan Nijtmans  <nijtmans@users.sf.net>

	* tcl.m4: add some cross-compile support, borrowed from Tcl 8.6

2010-09-16  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: correct HP-UX LDFLAGS (only used when building big shell)

2010-09-14  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: add extra if check for .manifest file generation
	Add notice about package name and version being built.

2010-09-09  Jan Nijtmans  <nijtmans@users.sf.net>

	* tcl.m4: [FREQ #3058486] TEA_LOAD_CONFIG doesn't set all BUILD_ vars
	Slightly related: defining BUILD_$1 on all platforms - not only win -
	allows the -fvisibility feature to be used in extensions as well, at
	least if you compile against tcl >= 8.5.

2010-08-26  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: ensure safe quoting for autoheader usage

2010-08-19  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: add TEA_ADD_CLEANFILES macro to make adding cleanfiles
	easier, and add *.exp to CLEANFILES Windows default.
	(TEA_MAKE_LIB): Enhanced to check for MSVC that requires manifests
	and auto-embed it into proj DLL via MAKE_SHARED_LIB.  Also define
	VC_MANIFEST_EMBED_DLL and VC_MANIFEST_EMBED_EXE that do the same
	magic in case it is needed for extended TEA projects.

2010-08-16  Jeff Hobbs  <jeffh@ActiveState.com>

	*** Bump to TEA_VERSION 3.9 ***
	If upgrading from TEA_VERSION 3.8, copy over tcl.m4, change
	TEA_INIT to use 3.9 and reconfigure (ac-2.59+).
	BUILD_${PACKAGE_NAME} will be auto-defined on Windows for
	correct setting of TCL_STORAGE_CLASS.
	TEA_LOAD_CONFIG users should remove the SHLIB_LD_LIBS setting done
	in configure.in (LIBS will be automagically populated by
	TEA_LOAD_CONFIG).
	TEA_EXPORT_CONFIG has been added for ${pkg}Config.sh creators
	SHLIB_LD_FLAGS was deprecated a while ago, remove it if it is
	still in your Makefile.in.

	* tcl.m4: add /usr/lib64 to set of auto-search dirs. [Bug 1230554]
	Auto-define BUILD_$PACKAGE_NAME so users don't need to.  This
	needs to correspond with $pkg.h define magic for TCL_STORAGE_CLASS.
	Auto-define CLEANFILES.  Users can expand it.
	(SHLIB_LD_LIBS): define to '${LIBS}' default and change it only if
	necessary.  Platforms not using this may simply not work or have
	very funky linkers.
	(TEA_LOAD_CONFIG): When loading config for another extension,
	auto-add stub libraries found with TEA_ADD_LIBS.  Eases
	configure.in for modules like itk and img::*.
	(TEA_EXPORT_CONFIG): Add standardized function for exporting a
	${pkg}Config.sh.  See use by img::* and itcl.

2010-08-12  Jeff Hobbs  <jeffh@ActiveState.com>

	*** Bump to TEA_VERSION 3.8 ***
	If upgrading from TEA_VERSION 3.7, copy over tcl.m4, change
	TEA_INIT to use 3.8 and reconfigure (ac-2.59+).
	No other changes should be necessary.

	* tcl.m4: remove more vestigial bits from removed platforms.
	Add back SCO_SV-3.2*.
	Remove use of DL_LIBS and DL_OBJS and related baggage - these are
	only needed by the core to support 'load'.
	Allow for macosx in TEA_ADD_SOURCES.
	Correct check for found_xincludes=no in TEA_PATH_UNIX_X.

2010-08-11  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: remove the following old platform configurations:
	UNIX_SV*|UnixWare-5*, SunOS-4.*, SINIX*5.4*, SCO_SV-3.2*<readded>,
	OSF1-1.*, NEXTSTEP-*, NetBSD-1.*|FreeBSD-[[1-2]].*, MP-RAS-*,
	IRIX-5.*, HP-UX-*.08.*|HP-UX-*.09.*|HP-UX-*.10.*, dgux*,
	BSD/OS-2.1*|BSD/OS-3*
	(AIX): drop AIX-pre4 support and use of ldAix, use -bexpall/-brtl

2010-07-05  Jan Nijtmans  <nijtmans@users.sf.net>

	* tcl.m4: [Patch #1055668] removal of exported internals from
	tclInt.h (EXTERN macro)

2010-04-14  Jan Nijtmans  <nijtmans@users.sf.net>

	* tcl.m4    - Backport a lot of quoting fixes from tcl8.6/unix/tcl.m4
	            - Fix determination of CYGPATH for CYGWIN
	  With those fixes, itcl and tdbc compile fine with CYGWIN

2010-04-06  Jan Nijtmans  <nijtmans@users.sf.net>

	* install-sh         [Bug 2982540] configure and install* script files
	                     should always have LF

2010-02-19  Stuart Cassoff  <stwo@users.sourceforge.net>

	* tcl.m4: Correct compiler/linker flags for threaded builds on
	OpenBSD.

2010-01-19  Jan Nijtmans  <nijtmans@users.sf.net>

	* tcl.m4: Detect CYGWIN variant: win32 or unix

	together with SHLIB_LD definition to unbreak building on HPUX.

2009-03-20  Andreas Kupries  <andreask@activestate.com>

	* tclconfig/tcl.m4: Changed SHLIB_LD definition to unbreak
	building on HPUX.

2009-03-16  Joe English  <jenglish@users.sourceforge.net>

	* tcl.m4(TEA_PUBLIC_TK_HEADERS): Look at ${TK_INCLUDE_SPEC}
	(found in tkConfig.sh) when trying to guess where tk.h might be
	[Patch 1960628].

2009-03-11  Joe English  <jenglish@users.sourceforge.net>

	* tcl.m4: Allow ${SHLIB_SUFFIX} to be overridden at
	configure-time [Patch 1960628].  Also fix some comment typos,
	and an uninitialized variable bug-waiting-to-happen.

2008-12-21  Jan Nijtmans  <nijtmans@users.sf.net>

	* tcl.m4: [Bug 2073255] Tcl_GetString(NULL) doesn't crash on HP-UX
	          (this bug report was for Tcl, but holds for TEA as well.)

2008-12-20  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4: sync with tdbc tcl.m4 changes
	(SunOS-5.11): Sun cc SHLIB_LD: use LDFLAGS_DEFAULT instead of LDFLAGS

2008-12-02  Jeff Hobbs  <jeffh@ActiveState.com>

	*** Bump to TEA_VERSION 3.7 ***

	* tcl.m4: in private header check, check for <plat>Port.h instead
	of Int.h to ensure all private headers are available.

2008-11-04  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (Darwin): sync TEA_PRIVATE_TK_HEADERS handling of
	Tk.framework PrivateHeaders with TEA_PRIVATE_TCL_HEADERS.

2008-11-04  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4 (TEA_PATH_TCLCONFIG, TEA_PATH_TKCONFIG): exit with error
	when tclConfig.sh cannot be found. [Bug #1997760]
	(TEA_PRIVATE_TCL_HEADERS, TEA_PRIVATE_TK_HEADERS): allow for
	finding the headers installed in the public areas, e.g. a result of
	make install-private-headers. [Bug #1631922]

2008-08-12  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (Darwin): link shlib with current and compatiblity version
	flags; look for libX11.dylib when searching for X11 libraries.

2008-02-01  Donal K. Fellows  <donal.k.fellows@man.ac.uk>

	* tcl.m4 (TEA_CONFIG_CFLAGS): Updated to work at least in part with
	more modern VC versions. Currently just made the linker flags more
	flexible; more work may be needed.

2007-10-26  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (Darwin): add support for 64-bit X11.

2007-10-23  Jeff Hobbs  <jeffh@ActiveState.com>

	*** Tagged tea-3-branch to start TEA 4 development on HEAD ***

2007-09-17  Joe English  <jenglish@users.sourceforge.net>

	* tcl.m4: use '${CC} -shared' instead of 'ld -Bshareable'
	to build shared libraries on current NetBSDs [Bug 1749251].

2007-09-15  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4: 	replace all direct references to compiler by ${CC} to
			enable CC overriding at configure & make time.
	(SunOS-5.1x):	replace direct use of '/usr/ccs/bin/ld' in SHLIB_LD by

	* tcl.m4: add caching to -pipe check.

2007-01-25  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4: integrate CPPFLAGS into CFLAGS as late as possible and

	arch flags from CFLAGS like in the Tk configure, as neither TkAqua nor
	TkX11 can be built for 64-bit at present.

2006-03-28  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: []-quote AC_DEFUN functions.

2005-12-05  Don Porter  <dgp@users.sf.net>

	* tcl.m4 (TEA_PUBLIC_*_HEADERS):	Better support for finding
	header files for uninstalled Tcl and Tk.

2005-01-25  Daniel Steffen  <das@users.sourceforge.net>

	* tcl.m4 (Darwin): fixed bug with static build linking to dynamic
	library in /usr/lib etc instead of linking to static library earlier
	in search path. [Tcl Bug 956908]
	Removed obsolete references to Rhapsody.

2004-12-29  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: Updates for VC7 compatibility, fixing CFLAGS and LDFLAGS
	options, using better default -O levels. [Bug 1092952, 1091967]

2004-12-29  Joe English  <jenglish@users.sourceforge.net>

................................................................................
	of gcc to ${CC}.

2002-10-15  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: move the CFLAGS definition from TEA_ENABLE_SHARED to
	TEA_MAKE_LIB because setting too early confuses other AC_* macros.
	Correct the HP-11 SHLIB_LD_LIBS setting.

	* tcl.m4: add the CFLAGS definition into TEA_ENABLE_SHARED and
	make it pick up the env CFLAGS at configure time.

2002-10-09  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: add --enable-symbols=mem option to enable TCL_MEM_DEBUG.
	Improved AIX 64-bit build support, allow it on AIX-4 as well.
................................................................................
	Add TK_BIN_DIR to paths to find wish in SC_PROG_WISH.
	These move towards making TEA much more independent of *Config.sh.

2002-03-19  Jeff Hobbs  <jeffh@ActiveState.com>

	* tcl.m4: corrected forgotten (UN)SHARED_LIB_SUFFIX and
	SHLIB_SUFFIX defines for Win.
	(SC_PATH_X): made this only do the check on unix platforms.

2002-03-12  Jeff Hobbs  <jeffh@ActiveState.com>

	* README.txt: updated to reflect fewer files

2002-03-06  Jeff Hobbs  <jeffh@ActiveState.com>

................................................................................
	* installFile.tcl: Added updating of the modification time of
	  the target file whether we overwrote it or decided that it
	  hadn't changed.  This was necessary for us to be able to
	  determine whether or not a module install touched the file.

2001-03-08    Karl Lehenbauer <karl@procplace.com>

	* installFile.tcl: Added support for converting new-style (1.1+)
	  Cygnus drive paths to Tcl-style.

2001-01-15    <brent.welch@interwoven.com>

#                       as its value.
#       SHLIB_SUFFIX -  Suffix to use for the names of dynamically loadable
#                       extensions.  An empty string means we don't know how
#                       to use shared libraries on this platform.
#       LIB_SUFFIX -    Specifies everything that comes after the "libfoo"
#                       in a static or shared library name, using the $VERSION variable
#                       to put the version in the right place.  This is used
#                       by platforms that need non-standard library names.
#                       Examples:  ${VERSION}.so.1.1 on NetBSD, since it needs
#                       to have a version after the .so, and ${VERSION}.a
#                       on AIX, since a shared library needs to have
#                       a .a extension whereas shared objects for loadable
#                       extensions have a .so extension.  Defaults to
#                       ${VERSION}${SHLIB_SUFFIX}.
#       TCL_NEEDS_EXP_FILE -
#                       1 means that an export file is needed to link to a
#                       shared library.
#       TCL_EXP_FILE -  The name of the installed export / import file which
#                       should be used to link to the Tcl shared library.
#                       Empty if Tcl is unshared.
#       TCL_BUILD_EXP_FILE -
#                       The name of the built export / import file which
#                       should be used to link to the Tcl shared library.
#                       Empty if Tcl is unshared.
