glibmm r809 - in trunk: . build_shared examples scripts tests tools/extra_defs_gen

Author: daniel
Date: Thu Mar 26 13:18:32 2009
New Revision: 809
URL: http://svn.gnome.org/viewvc/glibmm?rev=809&view=rev

Log:
Use DK_ARG_ENABLE_WARNINGS() to replace custom M4 macro

* scripts/dk-warn.m4: New file defining DK_ARG_ENABLE_WARNINGS().
* scripts/macros.m4: Remove the old GTKMM_ARG_ENABLE_WARNINGS().
* configure.in: Use new macro DK_ARG_ENABLE_WARNINGS() to set the
Makefile variable $(GLIBMM_WXXFLAGS).
* build_shared/Makefile_build.am_fragment (all_includes): Prepend
$(GLIBMM_WXXFLAGS).
* tools/extra_defs_gen/Makefile.am (INCLUDES): ditto,
* examples/Makefile.am_fragment (all_includes): ditto,
* tests/Makefile.am_fragment (INCLUDES): ditto.
