Thanks.

Could the __PRO__ (or something similar) be part of the cpp predefines
for this
configuration so non-gcc assembly can do the right thing?  I know that
at least
libgloss and RTEMS have hppa assembly.

Of course, this all begs the bigger question... how many embedded hppa
users
are there really? :)
