The example program has an O_TRUNC open call at the end, and I tried it with
a long name and it seemed to keep the old name fine.  I should close the
previous handle to the file in the test to make sure, but I didn't see 
this a a problem.

I had actually planned to add both the direct findfirst and stat calls to
the test program to record their behavior on the various platforms.

I also tested the new _open code on Windows NT 4.0 with the LFN TSR and
all seems OK.
