88fec49fbb re PR fortran/36112 (Bounds-checking on character length not working for array-constructors)
2008-06-17  Daniel Kraft  <d@domob.eu>

	PR fortran/36112
	* array.c (gfc_resolve_character_array_constructor):  Check that all
	elements with constant character length have the same one rather than
	fixing it if no typespec is given, emit an error if they don't.  Changed
	return type to "try" and return FAILURE for the case above.
	(gfc_resolve_array_constructor):  Removed unneeded call to
	gfc_resolve_character_array_constructor in this function.
	* gfortran.h (gfc_resolve_character_array_constructor):  Returns try.
	* trans-array.c (get_array_ctor_strlen):  Return length of first element
	rather than last element.
	* resolve.c (gfc_resolve_expr):  Handle FAILURE return from
	gfc_resolve_character_array_constructor.
