579 There are 2 unrelated problems with these functions under Mac:
580 a) Metrowerks MSL CRT implements them strictly in C99 sense and
581 doesn't support (very common) extension of allowing to call
582 mbstowcs(NULL, ...) which makes it pretty useless as you can't
583 know the size of the needed buffer
584 b) OS X <= 10.2 declares and even defined these functions but
585 doesn't really implement them -- they always return an error
586
587 So use our own replacements in both cases.
