--- Comment #29 from Alexander Monakov <amonakov at gcc dot gnu.org> ---
Note that Darwin opts out of flag_math_errno in common/config (which is also
per-cpu-target, so the same code is duplicated for powerpc):

/* Implement TARGET_OPTION_INIT_STRUCT.  */

static void
ix86_option_init_struct (struct gcc_options *opts)
{
  if (TARGET_MACHO)
    /* The Darwin libraries never set errno, so we might as well
       avoid calling them when that's the only reason we would.  */
    opts->x_flag_errno_math = 0;
