D'oh! OK - everything I said before is right, but... I tried the
following, and it led me up the right path.

$ ls -l /usr/lib/libc.so
libc.so 178 bytes (to cut a long story short)
That didn't look right, so I checked...
$ rpm -qf /usr/lib/libc.so
glibc-devel-2.1.91-18

Ahhh! The mist falls. Upgrade glibc-devel, all's well. But why??? Well, 
$ cat /usr/lib/libc.so
/* GNU ld script
   Use the shared library, but some functions are only in
   the static library, so try that secondarily.  */
GROUP ( /lib/libc.so.6 /usr/lib/libc_nonshared.a )

$ nm /usr/lib/libc_nonshared.a | grep atexit
atexit.oS:
         U __cxa_atexit
00000000 T atexit

aha! I don't know what changed, but I'd assume that atexit didn't
existin the old libc_nonshared.a (or equivalent), or that the old redhat
/usr/lib/libc.so failed to specify a static lib - anyone on a RedHat 7.0
or 6.95 box verify that in glibc 2.1.91?

Thanks for the help,
Dave.
