 413         There are 2 unrelated problems with these functions under Mac:
 414             a) Metrowerks MSL CRT implements them strictly in C99 sense and
 415                doesn't support (very common) extension of allowing to call
 416                mbstowcs(NULL, ...) which makes it pretty useless as you can't
 417                know the size of the needed buffer
 418             b) OS X <= 10.2 declares and even defined these functions but
 419                doesn't really implement them -- they always return an error
 420
 421         So use our own replacements in both cases.
