* trans-expr.c (gfc_conv_function_call): Remove the default
initialization of intent(out) derived types.
* symbol.c (gfc_lval_expr_from_sym): New function.
* matchexp.c (gfc_get_parentheses): Return argument, if it is
character and posseses a ref.
* gfortran.h : Add prototype for gfc_lval_expr_from_sym.
* resolve.c (has_default_initializer): Move higher up in file.
(resolve_code): On detecting an interface assignment, check
if the rhs and the lhs are the same symbol. If this is so,
enclose the rhs in parenetheses to generate a temporary and
prevent any possible aliasing.
(apply_default_init): Remove code making the lval and call
gfc_lval_expr_from_sym instead.
(resolve_operator): Give a parentheses expression a type-
spec if it has no type.
* trans-decl.c (gfc_trans_deferred_vars): Apply the a default
initializer, if any, to an intent(out) derived type, using
gfc_lval_expr_from_sym and gfc_trans_assignment. Check if
the dummy is present.
