[BRLTTY] Support multiple Python versions on Windows

[Leonard de Ruijter]

Hi Dave,


Thanks for the quick response.

May be I should setup a dev environment myself first to experiment a 
bit, but I'm slightly puzzled about the docs. What should I do if I want 
to create a x86 python module? Should I go with Cygwin or min-GW, and 
should it be explicitly X86 or can X64 builds of either cygwin or MinGW 
perfectly create X86 modules?


Cheers,

Leonard
