+ * gfortran.h: Extend gfc_code.ext.alloc to carry a

+ taken from expr3.
+ * resolve.c (resolve_allocate_expr): Add F2008 notify
+ and flag indicating source driven array spec.
+ (resolve_allocate_deallocate): Check for source driven
+ array spec, when array to allocate has no explicit
+ array spec.
+ * trans-array.c (gfc_array_init_size): Get lower and

+ the source expression is an array-constructor which is
+ fixed to be one-based.
+ (retrieve_last_ref): Extracted from gfc_array_allocate().
+ (gfc_array_allocate): Enable allocate(array, source=
+ array_expression) as specified by F2008:C633.
+ (gfc_conv_expr_descriptor): Add class tree expression
+ into the saved descriptor for class arrays.
+ * trans-array.h: Add temporary array descriptor to
+ gfc_array_allocate ().
+ * trans-expr.c (gfc_conv_procedure_call): Special handling
