	* app/diagram.h : added prototype for diagram_update_menu_sensitivity()
	* app/commands.c : give the right number of parameters
	to diagram_update_menu_sensitivity ()

	* app/preferences.c : do proper initialization for DiaPrefsData:
	render_bounding_boxes. It would be a real surprise if 'hidden'
	properties would have ever worked before.
	Don't try to access the widgets of hidden property, it does not
	have one.

	* lib/diagramdata.h : make render_bounding_boxes a DIAVAR, cause
	it is defined in libdia, but initialized from dia app, which
	otherwise gave nice start-up crashes.

	* lib/diagramdata.c : initialize the color for rendering bounding
	boxes in the Dia range (0 .. 1.0)

	* lib/libdia.def : added *_bbox functions for export

	* lib/makefile.msc : added new sources

	* objects/custom/custom_object.c : use HAVE_UNISTD_H
