542 There are 2 unrelated problems with these functions under Mac:
543 a) Metrowerks MSL CRT implements them strictly in C99 sense and
544 doesn't support (very common) extension of allowing to call
545 mbstowcs(NULL, ...) which makes it pretty useless as you can't
546 know the size of the needed buffer
547 b) OS X <= 10.2 declares and even defined these functions but
548 doesn't really implement them -- they always return an error
549
550 So use our own replacements in both cases.
