- Reply-to: sje at cup dot hp dot com
This is a patch to fix a problem I have when bootstrapping IA64 HP-UX.
This patch lets me get further along in the bootstrap but I am still
hitting other problems so I haven't been able to run a complete test on
this patch but it does get me further along and seems safe.
OK to check in?
