Each .pmc file has redundant function headings.  For example, in src/ 
pmc/integer.c
/*
=item C<PMC instantiate(PMC* sig)>
Create a new Integer with arguments passed according to pdd03.
=cut
*/
     PMC* instantiate(PMC* sig) {
         PMC* const ret = new_pmc_header(INTERP, 0);
         opcode_t *arg_op;
         INTVAL init = 0;
There's no reason pmc2c.pl can't create the =item line from the  
declaration of the function itself.  This removes double-maintenance  
for the programmer, and the chance of getting the two out of sync.
