We are continuing our long drawn out effort to port the SIMPL toolkit
(http://www.icanprogram.com/simpl) to the Cygwin platform. For a long time

As always, if you can provide test cases of bugs we will endeavor to fix
problems.

Here is some basic test code which illustrates all the things I spoke about in

In this Linux code snip we open the receive end of the fifo as RDWR (without
