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