With all respect, I think you're confusing things. I'm here trying to find some solutions for Python's build system (which, AFAIK, is about the development *of* Python), which I think is bogus on some systems. I'm just trying to better understand how it works here, and maybe send some patches if I find some solution for my problems. > > is there any problem when installing/using both > > 32- and 64-bit Python's on the same machine?

I was thinking about renaming the binary files, since they're (apparently) the only things that get overwritten *and* are dependent of the bit size (32/64). The rest of the files that would be overwritten, AFAIK, is not dependent of bitness so there's no problem at all. I think this may work (actually, I did the same thing successfuly with Perl). > > With two installation, use the header files you got from the 32-bit > install for 32-bit extensions/embedding, and the header files you > got from the 64-bit install for 64-bit extensions/embedding.

Since these files are the same (except for pyconfig.h, as you said), I assume that the reason for this separation is only for safety. I'll consider your proposal.
