What do C99 and POSIX say?

It seems strange for compilers to pick types when they are part of the
system ABI.

Isn't -fshort-wchar documented to deviate from the system ABI?  Isn't it
a bug to use it, unless you somehow want that behavior?


Or are you saying that -fshort-wchar is supposed use a fixed type, and
instead the compiler is picking up the system header?
