Add a check to configure that defines something like WINGUI_CFLAGS and
add those flags to the compilation command in the relevant Makefile.
Just a pick a check in configure and do some copy and paste.

For the moment you could just hardcode those values in the Makefile.
We can fix up these details later on.
