Yay!

Boo!
Well, we've had worse problems with Solaris in the past. We should certainly
put a note about the service pack in the installation instructions.
Is it reasonable to require the service pack be installed before making use of
any of this? My thinking is that, without location lists, anything except -O0
-g2 is going to be unusable, since most local variables will no longer have any
location data. At which point you might as well just stick with xcoff
debugging, yes?
