We should use GMP/MPFR from inside builtins.c to resolve things like e.g.
cos(0.12345) at compile-time.
Need to figure out:
1. Whether a certain minimum version of GMP/MPFR is required to avoid known
2. Whether we should include GMP/MPFR in the svn archive like we do for intl
3. Whether GMP/MPFR works on all the platforms/configurations that GCC
supports. Are we ready to require a GMP/MPFR port for every port of GCC?
4. If we don't do #2 and there is no system GMP/MPFR or the system lib is too
old, or if we trip over #3 and can't have GMP/MPFR, then what? Do we require
the user to go get/port it, or silently eliminate this optimization during the
Summary: transcendental functions with constant arguments should
be resolved at compile-time
