The third arg to strtol() specifies the base to assume for the number. When 0 is passed, as is currently done in wayland-client.c, hexadecimal and octal numbers are permitted and automatically detected and converted. exec-fd-leak-checker's single argument is the count of file descriptors it should expect to be open. We should expect this to be specified only as a decimal number, there's no reason why one would want to use octal or hexadecimal for that. Suggested by Yong Bakos.
