One issue with the Mercury front-end is that both GCC (toplev.c)
and the existing Mercury compiler want to be in control at the top
level -- to define main(), to handle argument passing, and so forth.
It would be a lot easier if toplev.c didn't define main(), but instead
defined say toplev_main(), and main() was instead defined in a new file,
called say main.c, to just call toplev_main(). Then I could build the gcc
back-end as a library. This would make it a lot easier to integrate
this back-end into the rest of the Mercury implementation's infrastructure.
Would such a change be acceptable?
