I'm using 2.5.1. How can I tell if I'm running on windows? The obvious answer, platform.system(), gets complicated. On the python that comes with cygwin, it returns 'CYGWIN_NT-5.2-WOW64', but I've got a native windows build of python where it returns 'Microsoft'.
The real problem I'm trying to solve is whether to build a LIBPATH environment variable with ';' or ':' delimiting the entries. On the cygwin build, os.pathsep returns ':', which isn't really correct. If you use that, you end up building paths that look like c:foo:c:bar. It should be c:foo;c:bar -- http://mail.python.org/mailman/listinfo/python-list
