I agree.

I may have misunderstood it, but perl's configure script appears 
to do something like this:

   if (symbol is in libc) {
       if (prototype looks like X) ...;
       else if (prototype looks like Y) ...;
       else if (prototype looks like Z) ...;
   }

and it probably blows up if the symbol is there with no prototype.
