The error variable breaks build on CentOS 6.7, due to
collision with global error symbol:
CC util/parse-events.o
cc1: warnings being treated as errors
util/parse-events.c:419: error: declaration of ‘error’ shadows a global
declaration
util/util.h:135: error: shadowed declaration is here
util/parse-events.c: In function ‘add_tracepoint_multi_event’:
...
Using different argument names instead to fix it.
