 421                doesn't support (very common) extension of allowing to call
 422                mbstowcs(NULL, ...) which makes it pretty useless as you can't
 423                know the size of the needed buffer
 424             b) OS X <= 10.2 declares and even defined these functions but
 425                doesn't really implement them -- they always return an error
 426
 427         So use our own replacements in both cases.
