I've attached a patch that leaves borland and g++ <= 4.0 as they were.
I also changed my little addition to the documentation to reflect
this. And one more thing, I couldn't find a macro analogous to
BOOST_MSVC for gcc's version number that I could use with
boost/config/compilers/gcc.hpp that does the same things as MPL's gcc
config file. Let me know if there's some other way this should have
been done.
