[issue24385] libpython27.a in python-2.7.10 i386 (windows msi release) contains 64-bit objects

[Matthew Barnett]

Matthew Barnett added the comment:

Here's how I can build the regex module on Windows 8.1, 64-bit, using only MinGW64.

For Python 3.5, I can link against "python35.dll", but for earlier versions, including Python 2.7, I need "libpython??.a".

I have built regex module for all of the 16 supported versions of Python (2.5-2.7, 3.1-3.5, 64-bit and 32-bit) and they have all passed the tests.
