Special function to work around an ommission in Win32s, which does not include the GetShortPathName function, even though Win32s is supposed to export ALL Win32 functions. This version does nothing under Win32s, which shortens pathnames automatically (?), under other versions of Windows it dynamically links to the function in the kernel32 library, thus avoiding an explicit link to the function which would prevent the app loading.
