[Python-Dev] Python should be easily compilable on Windows with MinGW

Sat Feb 27 17:14:02 EST 2016

Theoretically yes.  Practically, I think, but do not know for sure, it 
would have the same annoying issues as other SDK builds (of which, the 
most annoying is just different paths for the tools). Making that a 
supported build would require some of the same effort as supporting any 
other compiler though (a build bot configured to compile python this way).

I also think, but am not sure, that what you linked is in fact the 
leaner meaner toolchain that Steve was referring to.
