61 macro args. When -ftrack-macro-expansion is in effect, for macros
62 that have no arguments, create a macro map for the macro expansion

72 -ftrack-macro-expansion being < 2. Don't free macro arguments
73 memory resulting from expand_arg here, as these are freed by the
74 caller of replace_arg using delete_macro_args now. Push extended
