This is the right place, comp.lang.python might work too.

Use one of platform.system() or sys.platform, depending on the lowest
verion of python you want to support.

Not really. There is distutils.ccompiler.find_library_file() and
friends which you might put to good use, but I've never seen it being
used or used it myself. And it's quite complicated to get a usable
instance of CCompiler, expect to read distutils source.
But generally you can just use the platform default includes and then
it will simply fail to compile if they're not present.
