591 There are 2 unrelated problems with these functions under Mac:
592 a) Metrowerks MSL CRT implements them strictly in C99 sense and
593 doesn't support (very common) extension of allowing to call
594 mbstowcs(NULL, ...) which makes it pretty useless as you can't
595 know the size of the needed buffer
596 b) OS X <= 10.2 declares and even defined these functions but
597 doesn't really implement them -- they always return an error

599 So use our own replacements in both cases.
