By "dependency libraries" I meant hardcoding the path to a dependent 
library into the library needing the dependency (+b when creating a 
library).

Because I merged Ross's patch into the 1.4 branch, 
constructors/destructors don't come into play.

We're using HP CC/HP ld for our hppa64 work at present. Though we are 
also testing a GCC/HP ld for hppa64, we haven't tested it with libtool
yet (1.4 or 1.5).
