I'm pretty sure macros and such are gone before the C parser ever gets to see the token stream. But, it should be easy to pull out #define's on a second pass, using something like gcc $CFLAGS -E -dM myfile.h and then just scanning the output with a trivial "parser". (I'm not sure which of -dM, -dD, -dU you want.) -- Nathaniel _______________________________________________ cython-devel mailing list cython-devel@python.org http://mail.python.org/mailman/listinfo/cython-devel
