I'd suggest doing those in a system-neutral style too.  _copysign is a
function I take it.  In which case add autoconf tests and use
(untested),

        /* mingw offers _copysign rather than copysign */
        #if ! HAVE_COPYSIGN && HAVE__COPYSIGN
        #define copysign _copysign
        #define HAVE_COPYSIGN 1
        #endif

Again, good for adapting automatically to the future.  (Autoconf is
about testing for features, not system types.)

In principle hopefully not :-).  I needed to force
ac_cv_sys_restartable_syscalls=no when I tried a cross compile a while
ago though.

And an EXEEXT_FOR_BUILD is needed for gen-scmconfig.  I've been
meaning to propose some code I'd used for gmp in that area.

It's always annoying when autoconf does more than wanted.  Maybe
AC_CHECK_MEMBER should be used instead.
