Yes.

Hmm, good point.  I wonder how GNU ld does it...  Probably manually.

Well, it's always possible to do, by having the portability library
create a macro called "main", that translates that symbol to
"submain", and then define it's own main() that does the twiddling...

I think I've done that once upon a time, but I can't quite remember
for what...
