Add --enable-compile-warnings option to configure script.

Browse Source 
This patch adds the option to disable or enable compiler warnings
to maintain compatibility with gnome standard configure options, and
allow users to work around warnings from compiler incompatibility.

--enable-compile-warnings=no disables compile warnings completely,
while --enable-compile-warnings=yes turns on non-fatal warnings.
The default --enable-compile-warnings=error gives the previous behavior.

Dead code for enabling '-ansi -pendantic' is removed, and the
default enabling of -ansi is removed as well. Blanket disabling
GCC extensions and C99 features causes various problems; we're
better off enforcing the dialect we want to use at code review
time.
