Back out r26402 (as per r11054).

I've experimented with using 'gcc -pedantic' in lieu of 'gcc -std=c89'
(as suggested by ghudson in http://tinyurl.com/4265r), but it
complains loudly when compiling our dependencies, or even pulling in
their header files (e.g. APR).

* configure.in
  (CFLAGS): Stop adding -std=c89 (again) when gcc is detected, and we
   are in --enable-maintainer-mode.
