The compilers are g++ 2.96.x, the RedHat fork, and g++ 3.2. The
function I'm using for the test uses string objects from std namespace
and I'm about 99% sure the 2.96.x is handling them wrong. Guess I'll
stick with the nm|grep trick.

Am I going about this in the wrong way?
Since you are testing for a C++ function/method, AC_LANG should
definitely be set to C++. If the current C++ compiler is compatible
with the one used to build the library, then the symbol names should
be the same. It may be necessary to specify additional libraries in
order for the link to succeed. Check config.log for errors
encountered while running AC_CHECK_LIB in order to determine exactly
what is going wrong.
