this breaks compilation:
make[3]: Nothing to be done for 'plugins/libtraceevent-dynamic-list'.
util/parse-events.c: In function ‘parse_events_option’:
util/parse-events.c:2110:2: error: ISO C90 forbids mixed declarations and code [-Werror=declaration-after-statement]
2110 | int ret = parse_events(evlist, str, &err);
