I get the following error on powerpc-apple-darwin7.5.0 with gambc40b11:

This is in this strange code:

   if (d->emulate_terminal)
       /* forward declaration needed because lineeditor_output is 
recursive */

       ___HIDDEN ___SCMOBJ lineeditor_output_terminal_emulate
          ___P((___device_tty *self,
                ___C *buf,
                int len),

       d->emulate_terminal = 0;
       e = lineeditor_output_terminal_emulate (d, buf, len);
       d->emulate_terminal = 1;
     e = extensible_string_insert

Can you even have a forward declaration here?  Why not make 
declarations for all functions at the top of the file and not worry 
about it.  (It works when I move the declaration to the top level and 
leave out the local "declaration".)
