A change made to Mac/Makefile in r78813 for 2.6.5 does not work correctly when the --with-universal-archs=all (4-way) framework configure option is selected. The build of pythonw-64 fails with an incorrect gcc command: "gcc-4.0 64 -arch x86_64". The attached patch corrects the problem. Note, as documented in the 2.6.5 Mac/README file, the "all" variant can currently only be built on OS X 10.5. Run autoconf after applying to update configure.
