// windows.h #defines the following identifiers which are also used in wxWin so
// we replace these symbols with the corresponding inline functions and
// undefine the macro.
//
// This looks quite ugly here but allows us to write clear (and correct!) code
// elsewhere because the functions, unlike the macros, respect the scope.
