------- Comment #5 from jakub at gcc dot gnu dot org 2010-08-17 09:51 ------- The #c2 patch is problematic, because build_function_type shares function types, so setting TYPE_ARG_TYPES on that I'm afraid will affect all functions with (...) arguments and the same return type. So, the arglist needs to be passed down to gfc_get_function_type or wherever build_function_type is called. Furthermore, this doesn't help the case of functions that have no arguments (when we build_function_decl instead gfc_get_extern_function_decl, yet sym->formal is NULL or gfc_get_extern_function_decl for call noargsfn () ).
