Don't respond to drops when grab is in effect. (workaround)

Sat Mar 21 19:07:01 1998  Owen Taylor  <owt1@cornell.edu>

	* gtk/testgtk.c (dnd_drop): Don't respond to drops when
	  grab is in effect. (workaround)

	* gdk/gdkfont.c (gdk_fontset_load): More details on
	  error messages.

	* gdk/gdk.c: Translate va_list to XVaNestedList instead
	  of just casting it.

	* gtk/gtkmain.c: Make temporary copy of string returned by
	  setlocale, since it may be changed by subsequent calls.
