557 There are 2 unrelated problems with these functions under Mac:
558 a) Metrowerks MSL CRT implements them strictly in C99 sense and
559 doesn't support (very common) extension of allowing to call
560 mbstowcs(NULL, ...) which makes it pretty useless as you can't
561 know the size of the needed buffer
562 b) OS X <= 10.2 declares and even defined these functions but
563 doesn't really implement them -- they always return an error
564
565 So use our own replacements in both cases.
