// Borland C++ has the following nonstandard behaviour: when the -WU
// command line flag is used, the linker expects to find wWinMain instead
// of WinMain. This flag causes the compiler to define _UNICODE and
// UNICODE symbols and there's no way to detect its use, so we have to
// define both WinMain and wWinMain so that IMPLEMENT_WXWIN_MAIN works
// for both code compiled with and without -WU.
// See http://sourceforge.net/tracker/?func=detail&atid=309863&aid=1935997&group_id=9863
// for more details.
