Tiger you need to add "-isysroot /Developer/SDKs/MacOSX10.4u.sdk").
Note that configure requires CFLAGS to contain a least one architecture that can
be run on the build machine (i.e. ppc on G3/G4, ppc or ppc64 on G5, ppc or i386
on Core and ppc, i386 or x86_64 on Core2/Xeon).
Universal builds of Tcl TEA extensions are also possible with CFLAGS set as
above, they will be [load]able by universal as well as thin binaries of Tcl.

- To enable weak-linking, set the MACOSX_DEPLOYMENT_TARGET environment variable
to the minimal OS version the binaries should be able to run on, e.g:
	export MACOSX_DEPLOYMENT_TARGET=10.4
This requires at least gcc 3.1; with gcc 4 or later, set/add to CFLAGS instead:
	export CFLAGS="-mmacosx-version-min=10.4"
Support for weak-linking was added with 8.4.14/8.5a5.

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. '8.7').
