I am in favor of removing support for compilers that don't support partial
specialization, partial ordering and void returns, notably MSVC 6.0/7.0.
Dropping support for GCC < 3 would probably be uncontroversial as well. Not
sure about the others.

I wonder however how this should be done. Just removing the macro
definitions from the config compiler headers is not enough because people
can in principle use their own configs. Might it perhaps be better to leave
the compiler headers intact and just warn/#error in suffix.hpp when an
unsupported macro is set?
