annotate Python/bltinmodule.c @ 40053:693ff5d73412 2.4
Port of universal binary support for Mac OSX from python 2.5. This takes away
the need for the out-of-tree universal binary support that was used to build
the 2.4.3 installer.
Missing here relative to that tree are some changes to IDLE, IMHO those patches
aren't appropriate for the 2.4 branch and users are better of using 2.5's IDLE.
