MB_CUR_MAX is not required to be constant so the above may well be invalid on 
non-GCC.

conversion from wc to mb may require extra space for shift characters above 
MB_CUR_MAX. Completely bulletproof solution must check for resulting length 
and allocate buffer that is needed. Unfortunately it is not quite clear how 
to check length; wctomb(0, ...) does not return length, instead resets 
internal state.
