Re: [PATCH] fast-import.c: Silence build warning

gcc 4.3.3 (Ubuntu 9.04) warns that the return value of strtoul() was not
checked by issuing the following notice:

  warning: ignoring return value of ‘strtoul’, declared with attribute
warn_unused_result

Provide a dummy variable to keep the compiler happy.
