Sure, I use libbackend.a already.  The point is that I want a version
of it that doesn't define main().

I could put

	#define main toplev_main

in mercury/lang-options.h, I suppose.  Or perhaps in a new file
mercury/lang-main.h.  But I think it would be cleaner to avoid `#define main',
by doing it the way I described in my previous mail, with toplev.c defining
toplev_main() and with main() defined in a different file.
