A hosted implementation is required to support at least
two forms of main:
int main(void)
int main(int, char **)
Or int main(int argc,char* argv[]) most of the time.
Portable return values are 0, EXIT_SUCCESS and EXIT_FAILURE,
the latter two being declared in <stdlib.h>.
In C++ and C99, 'falling off' main, e.g.
int main()
{
/* no return */
}
... will result in a default of 0 being returned. C90
says that if the initial call to main fails to return a
value, then an unspecified termination status will be
returned to the host.
A free standing implementation need not even start via a
function called main.

I'm sure you've read otherwise Bill, and chosen to ignore
it...

Honestly this is the first time I've read this. I've been told otherwise and
I guess I was wrong. I seldom read the clc FAQS so that's my loss.
