We can use FreeBSDs version as role model, but we can't use the code verbatim, given FreeBSD assumes sizeof(wchar_t) == 4. Since that's a Cygwin-only issue (2 byte wchar_t, that is), I guess we should merge the code into the Cygwin code base, rather than newlib. For mbrtoc32/c32rtomb, we can use the wirtomb/mbrtowi function I introduced for the globbing code. If we do that, I think the functions should actually be renamed accordingly and the globbing code should use uchar32_t rather than wint_t. Also, it might be helpful to add the mbrtoc8/c8rtomb extensions at one point, which are missing in FreeBSD. Either way, I'd be grateful for patches in this area.
