Re: [PATCH] ctype: Fix bitfield types on 16-bit targets

Unfortunately that makes the code's correctness implementation-defined,
because it now depends on what the underlying implementation's take on
the constraint C99 6.7.2.1p4 is:
A bit-field shall have a type that is a qualified or unqualified
version of _Bool, signed int, unsigned int, or some other
implementation-defined type.
I.e. compilers are not required to allow uint32_least_t in this place.
