CFLAGS is supposed to work. That variable exists explicitly for the person building the sources to tweak; the configuration process shouldn't take it over for its own purposes. It should at most provide a convenient default value, but even that should be small enough that the user can override it easily; -O2 -g is okay. > 2.

If some Makefile.am or Makefile.in files have changed, you need to re-run config.status. If configure.in or aclocal.m4 have changed, you'll need to run configure again. The other approach is to get the right versions of libtool, automake, and autoconf installed (according to the README), and configure with --enable-maintainer-mode. Then `make' should do absolutely everything. It's a little unnerving.
