fenv*: Fix compilation error with mingw 13. It's caused by an ABI change in mingw: <https://sourceforge.net/p/mingw-w64/mingw-w64/ci/5c5973cf5f021db8fd75e9667e63881ccd169320/>. Reported by Collin Funk in <https://lists.gnu.org/archive/html/bug-gnulib/2025-04/msg00215.html>. * m4/fenv-environment.m4 (gl_FENV_ENVIRONMENT): Update comments for mingw 13. * lib/fenv-private.h (exceptions_to_x86hardware, x86hardware_to_exceptions): On mingw >= 13, define these like on MSVC. * lib/fenv-round.c (fegetround, fesetround): Do the safe mapping also on mingw >= 13. * lib/fenv-except-state-set.c (fesetexceptflag): Do the exceptions_to_x86hardware conversion also on other platforms than MSVC. * lib/fenv-except-tracking-clear.c (feclearexcept): Likewise. * lib/fenv-except-tracking-set.c (fesetexcept): Likewise. * lib/fenv-except-trapping.c (feenableexcept, fedisableexcept, fegetexcept): Do the exceptions_to_x86hardware and x86hardware_to_exceptions conversions also on other platforms than MSVC. * lib/fenv-env.c (fegetenv, fesetenv): Add new implementation for mingw >= 13. * doc/posix-functions/fesetenv.texi: Mention the new mingw bug. * doc/posix-functions/feupdateenv.texi: Mention the new mingw bug.
