This is probably best.
Warnings are easily lost in the noise.

libstdc++ is part of the gcc distribution.  It only has to work with a
single version of g++ -- whatever is in the same tree.

For C++ applications in general, g++ generally just tries to keep up
the standard and then someone fixes the apps.  They are in a different
situation, though, as there aren't really alternative C++ compilers on
Linux, so applications tend to get written to what works with g++.  On
the other hand, there are good java compilers, and mostly what we're
doing in Classpath is working around gcj bugs.
