[LLVMdev] Problem in External/SPEC/CFP2000/177.mesa/Makefile ?

Hello folks,

The makefile for 177.mesa says that for a small problem size, it will
get 100 frames. But in the spec sources I have, the test folder only
contains numbers for 10 frames:

$ speccpu2000/benchspec/CFP2000/177.mesa/data $ wc -l test/input/numbers
      10 test/input/numbers

Generating 100 frames causes undefined behaviour because the program is
doing unchecked fscanf on that "numbers" file.

Is my version of spec wrong ? If not, can we apply the attached patch ?
