Re: RCS-5.8.2 Re: rcs-5.7.96 build feedback

I suggest not bothering with the C99 syntax here.  Go with C11, and use 
the 'static' keyword.  That's the only thing that's likely to help an 
optimizing compiler anyway.  E.g., test this in 'configure':

int
main (int argc, char *argv[static argc])
{
    ...
}

and then use the version with 'static' if available.  Why waste time 
fiddling with the 15-year-old syntax?
