what i did is this:
in the Target settings in CW, there's a place to specify an include file.
by default, this is "Us.Prefix.h". i created a Us.Prefix.Foo.h file, which
is simply:
#define _FOO_
#include "Us.Prefix.h"
then i point the Target settings to my own "Us.Prefix.Foo.h" file, and
bingo, now i have _FOO_ defined only when compiling under CW for PalmOS.
