arith.c: Change conditional test for inclusion of arctangent().
2006-09-28 Steven G. Kargl <kargl@gcc.gnu.org> * arith.c: Change conditional test for inclusion of arctangent(). (gfc_check_real_range): Change conditional test for use of mpfr_subnormalize. * simplify.c (gfc_simplify_atan2): Fix conditional for use of mpfr_atan2() instead of arctangent(). (gfc_simplify_exponent): Fix conditional for use of mpfr_get_exp(). (gfc_simplify_log): Fix conditional for use of mpfr_atan2() instead of arctangent(). (gfc_simplify_nearest): Fix conditional for use of mpfr_nextafter(). From-SVN: r117289
