more hpux 10.20 trouble: bad gencodes.c file (gengenrtl prob)

The same behaviour with the 0115 snapshot, on hppa2.0-hp-hpux10.20 and
hppa1.1-hp-hpux11.0 . The genrtl.c and genrtl.h files are identical,
so that genrtl.h ends up including itself when referenced.
Debugging, the -h argument to gengenrtl is not recognized - the value of
argc is incorrect. If this has happened before it may be worth guarding
with a "cmp genrtl.h genrtl.c".

bash-2.02$ gdb gengenrtl
