2000-04-26  Jody Goldberg <jgoldberg@home.com>

	* src/gnumeric-util.c (gnumeric_glade_xml_new) : Use gnumeric_error_sys_err.

	* src/gutils.c (gnumeric_sys_{data,lib,glade,plugin)_dir) : New functions.
	(gnumeric_usr_dir, gnumeric_usr_plugin_dir) : New functions.

	* src/plugin.c (load_all_plugins) : Use

	* *.c : glade_new_xml -> gnumeric_glade_new_xml
	  Localize GNUMERIC_GLADEDIR so that plugins can use it too.

	* src/gnumeric-util.c (gnumeric_glade_xml_new) : New function.

	* */Makefile.am : Set 'DATADIR' rather than GLADEDIR.  And version
	  the glade file the same way the plugins are set.  This should
	  probably expand to include architecture akin to gcc.

	* src/widgets/widget-editable-label.c (el_button_press_event) :
	  Clicking in another window accepts the changes.  Once we have
	  reliquished our grab push the button event back on the queue
	  so that it can be forwarded on to the appropriate recipient (9007).

	* src/parse-util.c (parse_text_value_or_expr) : Watch for 1 character
	  strings which could start an expression.
