Matthias Clasen 269d89c79c Define macros GTK_PARAM_READABLE, GTK_PARAM_WRITABLE, GTK_PARAM_READWRITE
2005-03-21  Matthias Clasen  <mclasen@redhat.com>

	* gtk/gtkprivate.h: Define macros GTK_PARAM_READABLE,
	GTK_PARAM_WRITABLE, GTK_PARAM_READWRITE which are like
	their G_ counterparts, but also mark the name, nick
	and blurb as static.

	* gtk/*.c: Mark param spec strings as static, using
	the new macros.
