mingw does define WIN32, _WIN32, __WIN32 and even __WIN32__ for good
measure. I picked _WIN32 exactly because MSDN said that's the one
predefined by MSVC as well and thus can be used to detect the platform
without any headers included. Compiler-specific constructs (pragmas,
attributes, etc) should still be conditional on _MSC_VER, of course.

No idea about cygwin, but I guess these macros should only be defined
when using the windows headers/dlls and not when using the cygwin
layer. That would suit us fine, but we shall wait for a confirmation.
