573 There are 2 unrelated problems with these functions under Mac:
574 a) Metrowerks MSL CRT implements them strictly in C99 sense and
575 doesn't support (very common) extension of allowing to call
576 mbstowcs(NULL, ...) which makes it pretty useless as you can't
577 know the size of the needed buffer
578 b) OS X <= 10.2 declares and even defined these functions but
579 doesn't really implement them -- they always return an error
580
581 So use our own replacements in both cases.
