* unix/tcl.m4 (Darwin): add support for --enable-64bit on x86_64, for
universal builds including x86_64, for 64-bit CoreFoundation on Leopard
and for use of -mmacosx-version-min instead of MACOSX_DEPLOYMENT_TARGET.
* unix/configure: autoconf-2.13
* generic/tcl.h: add fixes for building on Leopard and support for
* unix/tclUnixPort.h: 64-bit CoreFoundation on Leopard.
* unix/tclUnixPort.h: on Darwin x86_64, disable use of vfork as it
causes execve to fail intermittently. (rdar://4685553)
* macosx/README: updates for x86_64 support and Xcode 2.3.
