gcc supplies low-level routines that implement doubleword arithmetic,
but it doesn't attempt to supplant the local libc.

I'm not eager to do it either --- I hope to have upgraded to HPUX 10
before I actually need to do anything with int8.  I was just throwing
that idea out in case someone else needed int8 bad enough to want to
make it happen.
