Sat Nov 17 18:26:45 2001 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am gtk/gtkmarshal.list gtk/gtkmarshalers.list gtk/*.c gtk/gtksignal.h: Make gtkmarshal.list/gtkmarshal.h only for compatibility with GTK+-1.2; and deprecate it; put all marshalers we actually use into gtkmarshalers.list and use the _gtk_marshal_ prefix for these marshalers.
