5/6/2006 Mac/OSX compile notes

Can't compile programs that use built-in math.h with either gcc-3.3 or 
gcc-4.0, e.g.

make blosum
/usr/bin/gcc-3.3 -Wall -O2 -c blosum.c
In file included from /usr/include/math.h:26,
                 from blosum.c:65:
/usr/include/architecture/ppc/math.h:349: error: parse error before "double"
make: *** [blosum.o] Error 1

Had to move "#include <math.h>" from blosum.c to motifj.h
