Warnings in unwind_protect

[Eyal Doron]

Hi,
   I'm performing an fscanf on a file, inside an unwind_protect block.
It now works, courtesy of a patch by John. However, fscanf still reports
warnings when it can no longer properly parse the input. While not
crucial, these warnings are irritating, since I'm already taking care
of that using the unwind_protect structure. Any way of getting rid of them?
