- unbreak on hppa (tested by landry@)
If you are upgrading from an older release (e.g. 5.6.x) it is advised to
read the upgrading guide which is available from
http://www.swi-prolog.org/Upgrade-5.8.html
Zap a -O3 from packages/semweb and honor our CFLAGS instead (also
noticed by steven@). No ok (or any feedback at all) for this. But I'm
pretty sure it doesn't break *%&$#@
