re PR fortran/13930 (derived type with intent(in) attribute not accepted)

	PR fortran/13930
	* decl.c (add_init_expr_to_sym): Remove incorrect check.
	(default_initializer): Move to expr.c.
	(variable_decl): Don't assign default initializer to variables.
	* expr.c (gfc_default_initializer): Move to here.
	* gfortran.h (gfc_default_initializer): Add prototype.
	* resolve.c (resolve_symbol): Check for illegal initializers.
	Assign default initializer.
testsuite/
	* gfortran.fortran-torture/execute/der_init_4.f90: New test.
