231 There are 2 unrelated problems with these functions under Mac:
232 a) Metrowerks MSL CRT implements them strictly in C99 sense and
233 doesn't support (very common) extension of allowing to call
234 mbstowcs(NULL, ...) which makes it pretty useless as you can't
235 know the size of the needed buffer
236 b) OS X <= 10.2 declares and even defined these functions but
237 doesn't really implement them -- they always return an error
239 So use our own replacements in both cases.

262 The system C library on Mac OS X 10.2 and below does not support
263 unicode: in other words all wide-character functions such as towupper et
264 al. do simply not exist so we need to provide our own in that context,
265 except for the wchar_t definition/typedef itself.
267 We need to do this for both project builder and CodeWarrior as
268 the latter uses the system C library in Mach builds for wide character
269 support, which as mentioned does not exist on 10.2 and below.

703 The systems where vsnprintf() supports positional parameters should
704 define the HAVE_UNIX98_PRINTF symbol.
706 On systems which don't (e.g. Windows) we are forced to use

723 The only compiler with positional parameters support under Windows
724 is VC++ 8.0 which provides a new xxprintf_p() functions family.
725 The 2003 PSDK includes a slightly earlier version of VC8 than the
726 main release and does not have the printf_p functions.

738 We always want to define safe snprintf() function to be used instead of

740 we really need...), otherwise we implement it using our own printf()

819 More Unicode complications: although both ANSI C and C++ define a number of
820 wide character functions such as wprintf(), not all environments have them.
821 Worse, those which do have different behaviours: under Windows, %s format
822 specifier changes its meaning in Unicode build and expects a Unicode string
823 while under Unix/POSIX it still means an ASCII string even for wprintf() and
824 %ls has to be used for wide strings.
826 We choose to always emulate Windows behaviour as more useful for us so even
827 if we have wprintf() we still must wrap it in a non trivial wxPrintf().
