Yeah.  It's valid, but not useful, I think.  I suppose someday
somebody might want to make it useful.

I think the bug would still occur with flag-syntax-only, since in this
case that flag would be 0.  I haven't looked at most of the uses of
this flag, though I recall adding one or two to the bytecode front end
to fix problems there that occurred when not generating any output.
(`gcj --syntax-only foo.class' is surprisingly useful; I use it all the
time to verify bytecode.)
