Why are you changing these variables from a HOST_WIDE_INT to 
unsigned longs?

The inclusion of stdlib.h should be conditional on HAVE_STDLIB_H.

You also can't just delete the atol extern -- I would think you
would want to have autoconf determine if it's needed.

I would advise against using atoq since I doubt it's a function we
can really depend on.

Is %llx something you can really rely upon?  I don't think so.  Is there
some way to handle this using standard format strings?

Sounds right.

See above about unsigned long vs HOST_WIDE_INT.

I think this is OK.

I'll just assume this is right :-)
