Including -R /usr/local/lib?

I believe this has been discussed in the past, you may want to search
the list archives. I would dislike g++ automatically adding -R options
to the binary. That way, you get binaries that work only on the
machine you compile on, and not on any other Solaris machine.

I recommend to use either of two solutions:
- configure egcs with --disable-shared, so you'll link libstdc++ 
  statically. This seems reasonable especially since the ABI of
  g++ is in the permanent state of flux (I believe since g++ 1).
- add the -R option to the spec file after installation. This is
  what we do in-house; we also add /usr/local/X11/lib. Since this
  is a site-specific configuration, I would not want g++ to do
  it by default.
