I can use '! [ feature.get-values architecture : $(condition) ] in ia64'
or I can use '[ os.platform ] != IA64' (I tested the latter during the
weekend). Which one is preferable?

Thank you for the proposal! I think, "parisc" as an architecture is fine.
For now, we can test PA-RISC as not ia64, but what if HP-UX is ported to a
different architecture? :-)

As for the instruction-set, I'm not sure how it is used. Why would we need
"pa-risc-1-0", pa-risc-1-1" and "pa-risc-2-0" instead of a single name?

Also, while we are at it: can we define OSPLAT for PA-RISC in jam.h:

# if defined( __hpux ) && defined( __hppa )
# define OSPLAT "OSPLAT=PARISC"
# endif

If there are no objections, I can make this change in the trunk.

Thanks again,
  Boris
