Fri Jan 16 23:59:01 2004 Matthias Clasen <maclas@gmx.de> The first part of the fix for #114351 (see also gdk-pixbuf/ChangeLog and po/ChangeLog): * gtk/gtkintl.h: * gdk-pixbuf/gdk-pixbuf-i18n.h: * gdk/gdkintl.h: Define P_() for property blurbs and nicks. * gdk/gdkdisplaymanager.c: * gdk-pixbuf/gdk-pixbuf.c: * modules/input/gtkimcontextxim.c: * gtk/*.c: Mark property blurbs and nicks with P_(). * po/Makefile.in.in: Add --keyword=P_ to the xgettext invocation, since property blurbs and nicks are now marked with P_().
