* m4/dk-warn.m4 (DK_ARG_ENABLE_WARNINGS): Accept a fourth argument
which can be used to generate -DMODULE_DISABLE_DEPRECATED defines
by specifying a list of module prefixes.  These flags are produced
only in --enable-warnings=fatal mode, in order to avoid breaking
the default build if new deprecations appear in some module.

* configure.ac (REGEXXER_WARNING_FLAGS): List the module prefixes
GLIBMM and GTKMM in the fourth argument to DK_ARG_ENABLE_WARNINGS.
* Makefile.am (global_defs): Remove -D*_DISABLE_DEPRECATED flags,
since they are now included in $(REGEXXER_WARNING_FLAGS).
