Re: Update Windows binaries (no pywin32 sub-problem)

[Vasily Galkin <galkin-vv yandex ru>]

As far as I remember my thoughts about pywin32 on msys after reading 
https://github.com/Alexpux/MINGW-packages/issues/751
shows that "it is not ready for msys".

Root of a problem is in a fact that pywin32 source code contains some visual-studio-specific parts and can't 
be compiled with mingw.
And visual studio build uses malloc/free from library that is used by visual studio (ucrtbase.dll i think). 
The version stored in pip repo is or official python for windows binary (which is compiled by VS2015).

But mingws' python is compiled with mingw and uses malloc/free from corresponding library (msvcrt.dll i 
think).

So I'm not sure there is simple way to use pywin32 with mingw64's python without changing pywin32 source code.
