OP commented below that he wants to pass the define into make and have it pass it on to GCC.

Make does not allow this. Typically you just add another make rule to add defines. For instance 'make release' vs 'make debug'. As the makefile creator you make the two rules and have the defines right in the make file. Now if Eclipse is not putting the defines into the makefile for you, I would say Eclipse is broken.
