Owen Taylor a036c6e59f Make gtkmarshal.list/gtkmarshal.h only for compatibility with GTK+-1.2; 
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.
