A word of warning... with 7.0, libsetjmp will go away.  ld(1) will be smart
enough to use the 'old' setjmp (called v0_setjmp) in libc when necessary,
but standard HP-UX libraries will be shipped fully optimized, so you
may get errors about floating point incompatibilities when mixing 6.2 and 7.0.

It depends on what you are trying to do.  Mixing 6.5 object files with 6.2
libraries may fail with either linker (that is, there are cases with each
where it *will* fail), but mainly if you compile for the 68010.  These can
mostly be worked around - compiler generated function calls for things like
"long" division changed from ldiv to __ldiv, so just define __ldiv,
and have it call ldiv, and 6.5 object files will then happily link to 6.2
libraries.  This sort of thing is *NOT* supported.
