freopen() Broken in F15

[Chuck Forsberg WA7KGX N2469R]

>In short: the code you sent is broken - fix it.  See figure.1

The original code was written by Bill Joy back in the 70s.
It has been tweeked and recompiled a number of times over the years
as changes in operating system caused the previous binary to
abend with a diagnostic.

But it is a bit spooky when a program just stops working for
no obvious reason.  In the case of this particular program,
the breakage is easy to spot and a workaround devised.
We should always be so lucky.
