A remark about installing with GMP 5. On Gentoo I had to apply the
following
for it to compile
{{{
# fixes for gmp-5
sed -i "s:__GMP_BITS_PER_MP_LIMB:GMP_LIMB_BITS:g" bestd.c mpmod.c
\
schoen_strass.c sp.h || die "failed to patch files for
gmp-5"
}}}
This is backward compatible with GMP 4.3. I am a bit surprised that with
the stuff
that mpir has deprecated, they didn't deprecate that as well.
