	* generic/tclDTrace.d (new file): add DTrace provider for Tcl; allows
	* generic/tclCompile.h:		  tracing of proc and command entry &
	* generic/tclBasic.c: 		  return, bytecode execution, object
	* generic/tclExecute.c:		  allocation and more; with essentially
	* generic/tclInt.h:		  zero cost when tracing is inactive;
	* generic/tclObj.c:		  enable with --enable-dtrace configure
	* generic/tclProc.c:		  arg (disabled by default, will only
	* unix/Makefile.in:		  enable if DTrace is present).
	* unix/configure.in:		  [Patch 1793984]

	* macosx/GNUmakefile:		  enable DTrace support.
	* macosx/Tcl-Common.xcconfig:
	* macosx/Tcl.xcodeproj/project.pbxproj:

	* generic/tclCmdIL.c:	factor our core of InfoFrameCmd() into internal
				TclInfoFrame() for use by DTrace probes.

	* unix/configure: autoconf-2.59
	* unix/tclConfig.h.in: autoheader-2.59

2007-09-12  Don Porter  <dgp@users.sourceforge.net>

	* unix/Makefile.in:	Perform missing updates of the tcltest Tcl
	* win/Makefile.in:	Module installed filename that should have
	been part of the bump to tcltest 2.3b1.  Thanks Larry Virden.
