They shouldn't be, and aren't for other compilers, and in fact the member
function pointers that are tested in the test suite don't get mis-assigned
as class types, even with gcc.  I accept that there is a problem with gcc
though because <T U::*> partial specialisations don't pick up member
function pointers as it should, so we ended up with a long list :-(
