-- with gcc use the same options, but use grpof instead of prof
Or: call gettimeofday before the copy function is called, and then call it again after.
Subtract the two timeval structs to get the time.

"last_pass_time"
The last time the test program passed, in seconds from the epoch.
Returns "undef" if the program has never passed.
