glib/gobject/gparamspecs.c
Tim Janik 009942e1ac made config arg to g_scanner_new() const. 
Fri Mar  9 18:01:43 2001  Tim Janik  <timj@gtk.org>

        * gscanner.[hc]: made config arg to g_scanner_new() const.

Fri Mar  9 16:42:08 2001  Tim Janik  <timj@gtk.org>

        * gvaluetypes.[hc]: moved g_strdup_value_contents() into this file as
        a public function (was static in gobject.c before). it's a bit odd
        to have that function here, especially since it requires extra includes,
        but then it doesn't very well fit somewhere else either.

        * gparamspecs.c: added default/max/min checks to param spec creation
        functions.
