87 that flag common block equivalences, emit an error if the
88 common blocks are different, using sym->common_head as the

106 module equivalences are made external, rather than local.

108 equivalences are marked as used. This prevents the subsequent
109 call to this function from making local unions.
110 * trans-decl.c (gfc_generate_function_code): Move the call to
111 gfc_generate_contained_functions to after the call to
112 gfc_trans_common so the use-associated, contained common

140 (gfc_apply_interface_mapping_to_expr)
141 (gfc_apply_interface_mapping): New functions.
142 (gfc_conv_function_call): Evaluate the arguments before working
143 out where the result should go. Make the null pointer case provide
144 the string length in parmse.string_length. Cope with non-constant
145 string lengths, using the above functions to evaluate such lengths.
146 Use a temporary typespec; don't assign to sym->cl->backend_decl.
