In floenv.c, some static functions need #ifdef protection to avoid errors
about unused functions.  See attached diff.  I found this on FreeBSD 13.1
where configure failed to detect floenv and so failed to define the following
macros:

HAVE_FEGETENV
HAVE_FESETEXCEPTFLAG
HAVE_FEGETEXCEPTFLAG

(In fact fegetenv is available on this OS.  If you want a spoiler for a future
bug report, configure tries to compile a file with the declaration "char
fegetenv ();" which is rejected by clang 14 due to -Wstrict-prototypes.)
