* resolve.c (resolve_assoc_var): Rearrange the logic for the
determination of the character length of associate names. If
the associate name is missing a length expression or the length
expression is not a constant and the target is not a variable,
make the associate name allocatable and deferred length.
* trans-decl.c (gfc_get_symbol_decl): Null the character length
backend_decl for deferred length associate names that are not
variables. Set 'length' to gfc_index_zero_node for character
associate names, whose character length is a PARM_DECL.
