I am looking into the CYGNUS_NEC references.

Is there any reason why you didn't segregate the code under the MB_CAPABLE macro 
like you did recently for vfprintf.c?  It would make sense to do it in 
conjunction with this change.

I also notice a number of formatting changes where the only change is moving the 
opening braces.  Is this due to your original code base?
