Is there no way around this problem? Does this mean we can't use
optimization with any code that uses any of the libps global
variables? If so this basically means none of the globals can be
used because everyone is going to want their stuff to run as fast
as possible by using optimization (I know I do!)

What a bummer :( especially when everythings OK
when using the -O0 switch... wee-urd!

BTW sceetech: what do you mean by 'a lot of things seem
to have been left *in* from the full libraries... ',
and what baring would this have on the problem?

Any help/info appreciated
