You could implement your own lockf() as a wrapper around fcntl(), assuming
that enough of fcntl() functionality actually exists (I did it once upon a
time for a really old LInux that didn't have lockf, and it actually worked!
however I don't own the code so I can't send it to you--it wasn't hard,
less than 100 lines of code, including whitespace and comments.)

I have no personal knowledge of the completeness of cygwin's fcntl() so
YMMV.

Good luck!

Fred
