 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? :)
