Actually, even without symbolic links there are problems.
(My previous example, however, failed to show that
since I ran g++ through a symbolic link.)
Here's another -v run that uses the exec-prefix path directly.
Notice the "non-existent" directories.  They are compiled into
the binary with lots of ../'s as explained in the original bug report.

A new link-free execution:

BTW: I'm installing a version with --with-gxx-include-dir, so if you have AFS
and want to try things out yourself, it won't be there anymore.
