I'd welcome it if some of the many failures in Boost.Math regression list on a few gcc platforms can

PS Perhaps adding a new section of 'Work in progress' on
https://svn.boost.org/trac/boost/wiki/Guidelines would be the best place for GCC C++ language
specification in relation to Boost?  

I have taken the liberty of adding Chris's  'knowledge'  to

https://svn.boost.org/trac/boost/wiki/Guidelines/GCCBoost

This is a wiki so others can add in their two-pennyworth...
