The g77 driver does this automatically. By "this" I mean adds -lg2c -lm.
In fact, I think if you specify -lg2c, it adds -lm after it; and if
you specify -lm, it adds -lg2c before it. Haven't tested that for
awhile. (But most of this is only since snapshot 19980615 or so;
before that, adding -lg2c -lm was done rather "mechanically".)
