  You seems to only consider late linking i.e. run-time one, and I'm
trying to explain that some systems need compile time linking informations
to be able to simply compile and link the program.

  Some systems have shared libraries, but can record dependancies to a
shared library only in a program instance, not in shared libraries. Not
everything is ELF or similarily capable. If you know your platform can do
it, fine, as I said provide a conditional patch, but you can't assume this
to be the case on all platforms. Just look at the bug which just landed
in the bugzilla during this exchange:
   http://bugzilla.gnome.org/show_bug.cgi?id=85161

  all platforms have serious divergences on the way they handle shared 
libraries, and what looks a simple optimization on platform A can simply
break linking on a whole set of other platforms, hence my request to make
this system specific.

  Just make the change Solaris specific, that's all !
