Something that may work would be to take the block of defines output by:

grep -p FP_MINUS_INF /usr/include/*

and add it to the math.h in the gcc directory.  I don't have a 4.2 box 
here so I can't test this, but the math.h in my gcc directory does 
contain the defines.  That math.h should be similar to the math.h in 
/usr/include.
