Thanks.  Not precisely the case, since I avoid using LD_LIBRARY_PATH, but it
led me to the answer.  The following files were in /lib:
 - libgcc_s-3.2-20020903.so.1
 - libgcc_s.so.1 (a symlink to the other file)
I deleted them, and my dynamically linked binary now works.  Apparently the
original RedHat 3.2 RPM put files in /lib, whereas the new one is using
/usr/lib.

compiler...

Yes, I am.  Of course I have the sources for several gcc versions sitting on
the machine so if I'm stuck I just have to bootstrap and install one of
those.  I also have the RPMs for a pre-built compiler on the same disk.  If
it ever comes to that, I guess I'll have to make sure I delete
/usr/lib/libgcc_s.so.1 (so far I've always been able to go forward on gcc
versions, rather than back).
