Hi Steffen,

(1) one way to do that is to append -Werror to CFLAGS after doing all sorts
of tests in configure.ac.  The tests always use the current value of CFLAGS.

(2) as noted by others, appending a mandatory(?) flag to CFLAGS is a bad
idea (and contradicts the GNU coding standards).  CFLAGS is one of the
variables passed from configure to Makefile that can also be specified on
the Make command line, i.e., `is reserved for the user'.
