* expr.c (is_subref_array): Add class pointer array dummies
to the list of expressions that return true.
* trans-array.c: Add SPAN_FIELD and update indices for
subsequent fields.
(gfc_conv_descriptor_span, gfc_conv_descriptor_span_get,
gfc_conv_descriptor_span_set, is_pointer_array,
get_array_span): New functions.
(gfc_get_descriptor_offsets_for_info): New function to preserve
API for access to descriptor fields for trans-types.c.
(gfc_conv_scalarized_array_ref): If the expression is a subref
array, make sure that info->descriptor is a descriptor type.
Otherwise, if info->descriptor is a pointer array, set 'decl'
and fix it if it is a component reference.
(build_array_ref): Simplify handling of class array refs by
passing the vptr to gfc_build_array_ref rather than generating
the pointer arithmetic in this function.
(gfc_conv_array_ref): As in gfc_conv_scalarized_array_ref, set
'decl'.
(gfc_array_allocate): Set the span field if this is a pointer
array. Use the expr3 element size if it is available, so that
the dynamic type element size is used.
(gfc_conv_expr_descriptor): Set the span field for pointer
assignments.
* trans-array.h: Prototypes for gfc_conv_descriptor_span_get
gfc_conv_descriptor_span_set and
gfc_get_descriptor_offsets_for_info added.

array, mark the declaration as a GFC_DECL_PTR_ARRAY_P. Remove
the setting of GFC_DECL_SPAN.
(gfc_trans_deferred_vars): Set the span field to zero in thge

* trans-expr.c (gfc_conv_procedure_call): Do not use copy-in/

(gfc_trans_pointer_assignment): Remove code for setting of
GFC_DECL_SPAN. Set the 'span' field for non-class pointers to
class function results. Likewise for rank remap. In the case
that the target is not a whole array, use the target array ref
for remap and, since the 'start' indices are missing, set the
lbounds to one, as required by the standard.
* trans-intrinsic.c (conv_expr_ref_to_caf_ref): Pick up the
'token' offset from the field decl in the descriptor.
(conv_isocbinding_subroutine): Set the 'span' field.

GFC_DECL_PTR_ARRAY_P.
(gfc_get_array_descr_info): Replaced API breaking code for
descriptor offset calling gfc_get_descriptor_offsets_for_info.
* trans.c (get_array_span): New function.
(gfc_build_array_ref): Simplify by calling get_array_span and

Glibc 2.17 made __secure_getenv an officially supported function, and
renamed it secure_getenv. The libgfortran configure has checked for
both of these, per
https://sourceware.org/glibc/wiki/Tips_and_Tricks/secure_getenv.
Unfortunately, while the dynamical library (libc.so) retains the
__secure_getenv symbol for backwards compatibility, the static library
(libc.a) does not. This means that a libgfortran.a compiled against an
older glibc will not work if one tries to link against a newer
libc.a. This creates problems for providing gfortran binary
distributions that work on as many target systems as possible.
Thus, retain the support for __secure_getenv but call it only via a
weak reference.
Regtested on x86_64-pc-linux-gnu.

In order to handle large character lengths on (L)LP64 targets, switch
the GFortran character length from an int to a size_t.
This is an ABI change, as procedures with character arguments take
hidden arguments with the character length.
I also changed the _size member in vtables from int to size_t, as
there were some cases where character lengths and sizes were
apparently mixed up and caused regressions otherwise. Although I
haven't tested, this might enable very large derived types as well.
Also, as there are some places in the frontend were negative character
lengths are used as special flag values, in the frontend the character
length is handled as a signed variable of the same size as a size_t,
although in the runtime library it really is size_t.
I haven't changed the character length variables for the co-array
intrinsics, as this is something that may need to be synchronized with
OpenCoarrays.
This is v4 of the patch. v3 was applied but had to reverted due to
breaking bootstrap. The fix is in resolve.c:resolve_charlen, where
it's necessary to check that an expression is constant before using
mpz_sgn.
Overview of v3 of the patch: All the issues pointed out by FX's review
of v2 have been fixed. In particular, there are now new functions
gfc_mpz_get_hwi and gfc_mpz_set_hwi, similar to the GMP functions
mpz_get_si and mpz_set_si, except that they get/set a HOST_WIDE_INT
instead of a long value. Similarly, gfc_get_int_expr now takes a
HOST_WIDE_INT instead of a long, gfc_extract_long is replaced by
gfc_extract_hwi. Also, the preliminary work to handle
gfc_charlen_type_node being unsigned has been removed.
Regtested on x86_64-pc-linux-gnu and i686-pc-linux-gnu.
