Having a nature of a project which activates a plugin just to munge the path automatically would be a little more streamlined. > > > As for CFLAGS/CPPFLAGS/LDFLAGS, I'm not sure why you want to set these when > running autoconf/automake/aclocal.

The motivation for changing these is that embedded development typically relies on a directory where the target's headers and libraries are accumulated. You need to instruct configure to look at that directory rather than the regular (build) system's ones. Thanks, Matt
