* dump-parse-tree.cc (show_code_node): Make output for SELECT
TYPE more comprehensible.
* expr.cc (find_inquiry_ref): Do not simplify expressions of
an inferred type.
* gfortran.h : Add 'gfc_association_list' to structure
'gfc_association_list'. Add prototypes for
'gfc_find_derived_types', 'gfc_fixup_inferred_type_refs' and
'gfc_change_class'. Add macro IS_INFERRED_TYPE.
* match.cc (copy_ts_from_selector_to_associate): Add bolean arg
'select_type' with default false. If this is a select type name
and the selector is a inferred type, build the class type and
apply it to the associate name.
(build_associate_name): Pass true to 'select_type' in call to
previous.
* parse.cc (parse_associate): If the selector is inferred type
the associate name is too. Make sure that function selector
class and rank, if known, are passed to the associate name. If
a function result exists, pass its typespec to the associate
name.
* primary.cc (resolvable_fcns): New function to check that all
the function references are resolvable.
(gfc_match_varspec): If a scalar derived type select type
temporary has an array reference, match the array reference,
treating this in the same way as an equivalence member. Do not
set 'inquiry' if applied to an unknown type the inquiry name
is ambiguous with the component of an accessible derived type.
Check that resolution of the target expression is OK by testing
if the symbol is declared or is an operator expression, then
using 'resolvable_fcns' recursively. If all is well, resolve
the expression. If this is an inferred type with a component
reference, call 'gfc_find_derived_types' to find a suitable
derived type. If there is an inquiry ref and the symbol either
is of unknown type or is inferred to be a derived type, set the
primary and symbol TKR appropriately.

expression references for a inferred type are consistent with
the now fixed up selector.
(resolve_assoc_var): Ensure that derived type or class function
selectors transmit the correct arrayspec to the associate name.
(resolve_select_type): If the selector is an associate name of
inferred type and has no component references, the associate
name should have its typespec. Simplify the conversion of a
class array to class scalar by calling 'gfc_change_class'.
Make sure that a class, inferred type selector with an array
ref transfers the typespec from the symbol to the expression.
* symbol.cc (gfc_set_default_type): If an associate name with
unknown type has a selector expression, try resolving the expr.
(find_derived_types, gfc_find_derived_types): New functions
that search for a derived type with a given name.
* trans-expr.cc (gfc_conv_variable): Some inferred type exprs
escape resolution so call 'gfc_fixup_inferred_type_refs'.
* trans-stmt.cc (trans_associate_var): Tidy up expression for

array references, passed as derived types.

'f2k_derived', if not set already, to point to the given
PDT template 'f2k_derived' namespace in order to give the
PDT instance referential access to the typebound procedures
of the template.
* gfortran.h (gfc_pdt_is_instance_of): Add prototype.
* resolve.cc (resolve_typebound_procedure): If the derived type
does not have the attribute 'pdt_template' set, compare the
dummy argument to the 'resolve_bindings_derived' type like usual.
If the derived type is a 'pdt_template', then check if the
dummy argument is an instance of the PDT template. If the derived
type is a PDT template, and the dummy argument is an instance of
that template, but the dummy argument 'param_list' is not
SPEC_ASSUMED, check if there are any LEN parameters in the
dummy argument. If there are no LEN parameters, then this implies
that there are only KIND parameters in the dummy argument.
If there are LEN parameters, this would be an error, for all
LEN parameters for the dummy argument MUST be assumed for
typebound procedures of PDTs.
(resolve_pdt): Add a check for ALLOCATABLE and POINTER attributes for
SPEC_DEFERRED parameters of PDT class symbols. ALLOCATABLE and
POINTER attributes for a PDT class symbol are stored in the
'class_pointer' and 'allocatable' attributes of the '_data'
component respectively.
