fenv.h: Change fexcept_t to integral type for compatibility
...
On Linux and in Mingw-w64, fexcept_t is defined as type unsigned short.
There are packages in the wild which rely on the fact that fexcept_t is
an integral type. We're changing the internal handling to use the bits
just as in GLibc, so only the 6 lowest bits are used to reflect the hw
bits. We even change the header file guard to reflect GLibc for compatibility.
* include/fenv.h (_FENV_H): Rename from _FENV_H_ and set to 1 as in
GLibc's header.
(fexcept_t): Change to __uint16_t to be an integral type as in GLibc.
* fenv.cc (fegetexceptflag): Align to the *flagp's type change.
(fesetexceptflag): Ditto.
