Hmm, when I run tests I load a new development environment module so somehow config is probably picking up the g++ in /usr/bin.  Yup, here's the old version:

gcc version 4.3.4 [gcc-4_3-branch revision 152973] (SUSE Linux) 

So guess we need to look at how config shells out the g++ command, it seems to be ignoring the environment used by the builds which do use the correct g++ from the environment.
