Enable GCC warnings in developer builds
However, do not fail; just issue the warnings. Add an option
--enable-gcc-warnings=warn-only to configure, to implement this.
* INSTALL, etc/NEWS: Document this.
* configure.ac (gl_GCC_VERSION_IFELSE): New macro, from coreutils.
(gl_gcc_warnings, WERROR_CFLAGS): Use it to add new option.
Don’t treat --with-x-toolkit=no as a special case when configuring
warnings.
