Most people on Linux build it themselves or one of the distribution 
packagers builds it for the distribution, I just put the binary rpm up 
because I need to build a binary to test the distribution so it's 
there.  I'm not sure how useful it is...

Actually, ATLAS is linked statically (AFAIK) so it is actually one 
benefit of a binary...

Yes... I wouldn't stress about the Linux binary.   But, I do think you 
need to test the binary build from the newly-created source distribution 
before uploading the tarball.

Again, I think it's statically linked.   I just do a bdist_wininst command.

If you don't have a distutils.cfg file, you do need to make sure and use 
config --compiler=mingw32 and build --compiler=mingw32 (unless you have 
the same compiler that built Python, then great...)

Best,
