[boost] Config questions for GCC 3.1

I'm suspicious of several macros reported by libs/config/config_info.cpp 
for GCC 3.1 (see macros section below):

Surely those can't be correct?

It would be helpful if someone knowledgeable about GCC could suggest fixes. 
They probably involve not just boost/config/compiler/gcc.hpp, but also 
boost/config/platform/cygwin.hpp, and boost/config/stdlib/libstdcpp3.hpp

Thanks,
