The 2.3.3 release of gcc (g++) included a fix for how virtual table
names are mangled.  This creates an inconsistency between names the
compiler generates, and the names in any libg++ created with a
compiler before 2.3.3.  For example, one of the most common problems
people will face as a result of this change will be an error that the
symbol `__vt$10ostrstream$3ios' is undefined at link-time.

It is necessary to build a new libg++.a with the latest (2.3.3)
compiler to sync things back up.  This would probably also be a good
opportunity to upgrade to the libg++ 2.3 release if you haven't yet.

Thanks, and my apologies for any inconvenience this may cause.
