That's fine but we shouldn't gratuitously break what support there is
for older versions of the compiler. For example, the configuration no
longer defines BOOST_NO_RVALUE_REFERENCES for older versions. So the
type traits library defines type traits using rvalue references which
fail to compile. This breaks a lot of boost that used to work with
pathscale 3.2. Some basic configuration for older versions would fix
that. I guess that in the past since there was no configuration file
for pathscale, the gcc file was used and was a close enough estimate
that some things worked, the new configuration file has removed that.
