Well, one can add

AC_CHECK_SIZEOF(long long)
AC_CHECK_SIZEOF(void*)
AC_CHECK_TYPES([intptr_t])

and then manually do something like

if test "$ac_cv_type_intptr_t" = "yes"

  intptr_fallback="intptr_t"

else

  if test "$ac_cv_sizeof_long" = "$ac_cv_sizeof_voidp";then
    intptr_fallback="long"
  else
    if test "$ac_cv_sizeof_long_long" = "$ac_cv_sizeof_voidp";then
      intptr_fallback="long long"
    else
    # crappy fallback
      intptr_fallback="size_t"
    fi
  fi

fi

Then, how do we add that to gmp-in.h / gmp.h ? that's
where I'm not sure..
