Look at the last include option. CFLAGS are being added on top of the INCLUDE_FLAGS (or whatever it's called).
does a simple cflags redefinition with a space in front work ?
seems to be a little bug in the configure script, although i don't run into it for some reason, maybe a space gets appended somewhere in the flow of the configure script before it gets to there (at least for me.) but added patch that should fix the problem.
