Tim Janik 2d68cbbb7d NEWS file update for upcoming release of GLib + GModule version 1.1.3,
Mon Sep 21 02:22:12 1998  Tim Janik  <timj@gtk.org>

        * NEWS file update for upcoming release of GLib + GModule
        version 1.1.3, binary age 0, interface age 0. (GModule uses
        the same version numbers as GLib.)

        * glib.h: swap the inclusion of of float.h and limits.h to work
        around a egcs 1.1 oddity on Solaris 2.5.1 (fix provided by
        Per Abrahamsen  <abraham@dina.kvl.dk>).

        * glib.h:
        * gscanner.c: renamed the GValue union to GTokenValue, this should
        not affect source compatibility in most cases.

        * ghash.c: added some g_return_if_fail() statements. make
        g_hash_table_lookup_node() an inline function so we save an extra
        function invokation on lookups.

Mon Sep 21 01:54:48 1998  Tim Janik  <timj@gtk.org>

        * gmodule.h:
        * gmodule.c: renamed old _de_init functionality to _unload.
        modules are now expected to export:
        G_MODULE_EXPORT const gchar* g_module_check_init (GModule *module);
        and
        G_MODULE_EXPORT void g_module_unload (GModule *module);
        returning a string other than NULL from g_module_check_init() will
        prevent the module from being loaded. a call to g_module_make_resident()
        from g_module_unload() will prevent the module from being unloaded and
        still make it resident.
