functions are either unimplemented or implemented differently. The source

assumes that for Windows NT, the macro 'MS_WINDOWS' is defined independent

of the compiler used. Different compilers define their own feature

test macro, e.g. '__BORLANDC__' or '_MSC_VER'. For OS/2, the compiler

independent macro PYOS_OS2 should be defined. On OS/2 the default

compiler is assumed to be IBM's VisualAge C++ (VACPP). PYCC_GCC is used

as the compiler specific macro for the EMX port of gcc to OS/2. */
