Should be Tag2,Tag1

Is <boost/mpl/aux_/numeric_op.hpp> the right file to
patch for this particular problem?  The header files
in the boost/mpl/aux_/preprocessed/gcc/ directory say
"DO NOT MODIFY".  Are they (the numeric ops)
pregenerated from this file?

If so, I've attached the diff to this message.
