Right, I misinterpreted your code.

To replace the explicit failures markup, we need a way to say "do not run 
this test on gcc-4.4, gcc-4.5, gcc-4.6, msvc-8.0, msvc-10.0", and it seems 
that we're either going to need logical operations for that, or a rule that 
is the opposite of predef-require, something like

[ predef-disable-if "BOOST_COMP_GCC == 4.4" "BOOST_COMP_GCC == 4.5" 
"BOOST_COMP_GCC == 4.6" "BOOST_COMP_MSVC == x.0" "BOOST_COMP_MSVC == y.0" ]

where x is whatever corresponds to msvc-8.0 and y - to msvc-10.0 :-)
