551 There are 2 unrelated problems with these functions under Mac:
552 a) Metrowerks MSL CRT implements them strictly in C99 sense and
553 doesn't support (very common) extension of allowing to call
554 mbstowcs(NULL, ...) which makes it pretty useless as you can't
555 know the size of the needed buffer
556 b) OS X <= 10.2 declares and even defined these functions but
557 doesn't really implement them -- they always return an error
558
559 So use our own replacements in both cases.
