565 There are 2 unrelated problems with these functions under Mac:
566 a) Metrowerks MSL CRT implements them strictly in C99 sense and
567 doesn't support (very common) extension of allowing to call
568 mbstowcs(NULL, ...) which makes it pretty useless as you can't
569 know the size of the needed buffer
570 b) OS X <= 10.2 declares and even defined these functions but
571 doesn't really implement them -- they always return an error
572
573 So use our own replacements in both cases.
