This statement in lang_specific_driver is responsible:
 /* If we saw no -O or -g option, default to -g1, for javac compatibility. */
 if (saw_g + saw_O == 0)
 arglist[j++] = "-g1";
That's done for a reason I guess, though it may be appropriate for use
with -C only.
Anyhow, it turns out the problem isn't gcj. Compiling c++ with -gdwarf-2
-g1 fails too. PR c++/2814 covers this.
Since it's a known regression, perhaps we should do nothing for now...
