  Gnulib module: fenv-environment
  
  Portability problems fixed by Gnulib:
  @itemize
  @item
  This function is missing on some platforms:
  FreeBSD 6.0, NetBSD 5.0, OpenBSD 3.8, Minix 3.1.8, AIX 5.1, IRIX 6.5, Solaris 9, Cygwin 1.7.7, MSVC 9, Android 4.4.
  @item
  This function does not work on some platforms:
  @c https://cgit.freebsd.org/src/commit/?id=34cc08e336987a8ebc316595e3f552a4c09f1fd4
  FreeBSD 12.2/arm64.
  @item
  This function does not restore the floating-point exception trap bits
  on some platforms:
  musl libc/i386, musl libc/x86_64, AIX 7.3, Solaris 10 and 11, MSVC 14.
  @item
  The macro @code{FE_DFL_ENV} cannot be used because it leads to a link error
  on some platforms:
  @c src/sys/arch/hppa/include/fenv.h src/lib/libm/arch/hppa/fenv.c
  NetBSD 10.0/hppa,
  @c src/sys/arch/{sparc,sparc64}/include/fenv.h src/lib/libm/arch/{sparc,sparc64}/fenv.c
  NetBSD 10.0/sparc,
  Cygwin 2.9.0.
  @item
  This function, when called with @code{FE_DFL_ENV} argument, has no effect
  on the x86 @code{mxcsr} register and thus on floating-point operations
  performed in the SSE unit on some platforms:
  mingw 10.
