"scratch" file bug in g77/egcs1.1b

[Dave Love]

I would have said something similar to Toon, but this has clearly
changed in f90/95 and libf2c should be compatible.  Thank you for the
reference to the standard -- that's what we like to see!

I can see where things have changed -- apparently due to syncing with
the Netlib version -- and will try to sort it out; some of the code
there is mine.

Thanks for the report.
