please be aware of the versioning on the C++ compiler

[Benjamin Kosnik]

Hey y'all. Recently patches went in to address some C++ ABI issues. 

For gcc:
http://gcc.gnu.org/ml/gcc-patches/2002-08/msg00174.html

For gcc-3_2-branch:
http://gcc.gnu.org/ml/gcc-patches/2002-08/msg01670.html

In the future, may I suggest that the following happen:

1) you add "C++ ABI change" to the ChangeLog entry.
2) you add notes to cp/NEWS for ABI breaks
3) you add a testsuite entry
4) you update __GXX_ABI_VERSION
5) you run 'make check-abi' in libstdc++-v3 in addition to make-check
6) if 5 breaks update the libstdc++.so

I don't consider this outlandish. Do you?
