 The behaviour seems fine to me.
 
 POSIX.1-2008 on
 http://www.opengroup.org/onlinepubs/9699919799/functions/strtol.html
 allows errno=EINVAL if no conversion could be performed (but the proper
 way to check this is via endptr).
 
 Common sense suggests that strtol("0", NULL, 0) be successful and return
 0, and in fact that is the case ("0" is an octal constant).
 
 "0x" should be interpreted as a subject sequence "0" followed by
 unrecognized sequence "x".
