The Xcode projects refer to the toplevel tcl source directory via the
TCL_SRCROOT user build setting, by default this is set to the project-relative
path '../../tcl', if your tcl source directory is named differently, e.g.
'../../tcl8.6', you need to manually change the TCL_SRCROOT setting by editing
your ${USER}.pbxuser file (located inside the Tcl.xcodeproj bundle directory)
with a text editor.

- To build universal binaries outside of the Xcode IDE, set CFLAGS as follows:
	export CFLAGS="-arch i386 -arch x86_64 -arch ppc"
This requires Mac OS X 10.4 and Xcode 2.4 (or Xcode 2.2 if -arch x86_64 is
omitted, but _not_ Xcode 2.1) and will work on any architecture (on PowerPC

Detailed Instructions for building with macosx/GNUmakefile
----------------------------------------------------------

- Unpack the Tcl source release archive.

- The following instructions assume the Tcl source tree is named "tcl${ver}",
(where ${ver} is a shell variable containing the Tcl version number e.g. '8.6').
Setup this shell variable as follows:
	ver="8.6"
If you are building from CVS, omit this step (CVS source tree names usually do
not contain a version number).

- Setup environment variables as desired, e.g. for a universal build on 10.5:
	CFLAGS="-arch i386 -arch x86_64 -arch ppc -mmacosx-version-min=10.5"
	export CFLAGS
