Are you sure it's legal to take "< 3" and paste on the remaining characters,
e.g., "0404"? My knowledge of the preprocesor is pretty limited, but this sounds
like something Paul M. told me was undefined.

You could also do

     BOOST_WORKADOUND(GCC, LESS(3,2,3))
     BOOST_WORKADOUND(GCC, LESS_EQ(3,2,3))
     BOOST_WORKADOUND(GCC, TESTED_AT(3,2,3))
     ...
