I had problems using C++ libraries built with 2.8.0 when changed to
2.8.1 (missing external symbols). This was as I tested specific to
2.8.0 only (not for gcc-2.7.2.1, gcc-2.8.1 and pgcc-1.0.1).

One example where I met this was in libstdcxx.a (classes istrstream,
ostrstream). So I think that such problems may be considered
serious reason to upgrade.
