159 name AND new attr field, in_equivalence.
160 * match.c (gfc_match_common, gfc_match_equivalence): In loops
161 that flag common block equivalences, emit an error if the
162 common blocks are different, using sym->common_head as the
163 common block identifier. Ensure that symbols that are equivalence

180 module equivalences are made external, rather than local.

182 equivalences are marked as used. This prevents the subsequent
183 call to this function from making local unions.
184 * trans-decl.c (gfc_generate_function_code): Move the call to
185 gfc_generate_contained_functions to after the call to
186 gfc_trans_common so the use-associated, contained common

215 (gfc_apply_interface_mapping): New functions.
216 (gfc_conv_function_call): Evaluate the arguments before working
217 out where the result should go. Make the null pointer case provide
