Re: 'static' in array-size func parm

[Paul Eggert]

I'd be interested in getting this to work in gnulib, but unfortunately 
it doesn't work yet with RCS so let's fix that first.

Actually, GCC 3.4.3 *can* compile that.  It just can't compile longer 
programs with that code in it.  Which, unfortunately, means that 
bleeding-edge RCS won't build on Solaris 10's GCC, as the configure-time 
test case succeeds but the actual compilation fails.  Please try the 
following program instead:

int
last (int count, int all[static count])
{
  return all[count - 1];
}
int
last1 (int count, int all[static count])
{
  return all[count - 1];
}

Perhaps I should also mention that the bug occurs with -O2 but does not 
occur when GCC is not optimizing.  This should work with the 
configure-time test, though, as it's built with -O2.
