[boost] Intel C++ for Linux defines __GNUC__!!

I don't know how or why this nastiness comes about, but it's true.
Just think of how many checks which look for __GNUC__ are foiled by
this one!

I am inclined towards a new policy for Boost which requires compiler
identification only via BOOST_-prefixed macros.  

If we do that, we can also ensure that BOOST_CONFIG #defines all of
them (mostly to zero) and we can eliminate the issues with warnings
from BOOST_WORKAROUND doing comparisons on macros which haven't been
defined.

Thoughts?
