The value returned (using "return") from main acts the same way as exit()
on my system:
return 0 will give a (successful) exit code of 1, but return 1 also gives
the same exit code.

In my opinion, the correct approach is to make gp_do_exit()
an empty function, and to handle the exit code (if needed)
in the return value from main() in gs.c. Does returning 0
from main() get treated as success or failure under VMS?
I removed nearly all occurences of exit in Ghostscript. The
remaining ones tended to be fatal error aborts.
exit is a very antisocial function to call in a DLL /
