C Ported to fortran by Kevin London
C If an event is countable but you've exhausted the counter resources
C and you try to add an event, it seems subsequent PAPI_start and/or
C PAPI_stop will causes a Seg. Violation.
C I got around this by calling PAPI to get the # of countable events,
C then making sure that I didn't try to add more than these number of
C events. I still have a problem if someone adds Level 2 cache misses
C and then adds FLOPS 'cause I didn't count FLOPS as actually requiring
C 2 counters.
