	* glib/gwin32.c (g_win32_get_windows_version): New
	function. Returns the Windows version code like GetVersion(),
	except that one can pretend to be running on Win9x by setting the
	G_WIN32_PRETEND_WIN9X environment variable. This is mainly for
	debugging purposed.

	* glib/gwin32.h: Declare it. Define macros G_WIN32_WINDOWS_IS_NT_BASED
	and G_WIN32_HAVE_WIDECHAR_API to test Windows features at run-time.
