I'm using GCC 2.95.2 that comes with Apple's developer tools. I'm
getting tempted to try compiling GCC 3.
Doing a grep for the above symbols returns matches for both the static
and dynamic libsqlplus libraries, as well as libstdc++.a, which is
automatically linked in with C++ code. I even tried manually adding
-lstdc++ but that didn't help. I've also tried defining various STL
options related to templates and several different compiler options,
without much success. Is this simply incompatible with GCC version
2.95.2?
