And given the state of flux of the C++ ABI and runtime libraries
under Linux, I'm personally not too fond of C++-compiled system libraries
right now. For instance, the SGI GLU included with the SGI ProPack 1.3
overlay has a runtime dependency on /usr/lib/libstdc++-libc6.1-1.so.2
(ouch). If you need to compile a program with a newer version of
g++ (for instance one of the 2.97 snapshots which installs its
own libstdc++ in /usr/local/lib)  where both the runtime
library and the ABI are incompatible, you are likely to run into
problems. I have no idea how this g++ ABI transition is going to be
handled...
