libgomp, libgcc and libssp are the shared libs of gcc.
(actually the correct libstdc++ and libgfortran are also found if the correct
libgcc is found as they never are linked in without it).
libgomp comes with an spec file that is installed into the lib dir.
I've added switches to gcc's configure to specify the link specs of these two
libs.
I've tested it and it works perfectly for me.

I think handling this via specs is the wrong (read: far too complicated)
approach.
I agree that gcc/g++/... not adding needed RPATHs to its runtime libraries is
a major nuissance for every site with more than a single system and a central
installation of gcc and it has bothered me for a long time.
I'm (slowly) working towards a generic approach to solve this problem, maybe
I'll have something ready for gcc 4.7.0.

Hi there,
it's always a pleasure to comment on an old thread. :-)

well, maybe, but at least it's better to have something
that works than having nothing.

well, anything done already? If not, what kind of solution do you have in mind?
Cheers, Olaf

Unfortunately not since I had to massively cut down my gcc work in
recent months.
The work consists of 3 parts, I think:
* A configure option to selectively enable/disable this since
unconditional enabling has found massive opposition in the past.
* Changing the build procedure so shared runtime libraries are
optionally build with RPATHs pointing at the installed locations of
their dependencies.
* Changing the drivers to add RPATHs for the shared runtime libraries
linked.
No idea when I'll get around to this, unfortunately.
