No, I did not compile PIC code. PIC and code coverage are incompatible
(on Solaris). So I compiled everything non-PIC, but sill in shared
libraries.

AFAIK, it ought to be ok, except the libraries will no be shared
accross processes, right ?

FYI, Sun ld refuses to link non-PIC in a shared lib. That's one of the
reasons why we're using GNU ld.
