Thanks for the STC. However, given how this stuff works internally,
I have no good solution off the top of my head. I played with various
ideas but to no avail. I add this to my TODO list, but I probably
won't have a quick solution :(
Thanks,
Corinna
P.S: It would be really helpful if you could stick to the original
thread and simply use "reply-to" once a discussion has started.
It's very confusing having to connect the various threads.
Thanks.
Perhaps David B. can be helped by a Cygwin-specific patching to "cmp"?
Eric?
... replacing the call to fstat() by a call to stat() ...
(as shown in https://cygwin.com/ml/cygwin/2015-12/msg00348.html)
By the way, thank you for reporting back to "us" about this. I already
feared that a "general" solution would have to wait ... You have already
too much on your plate.
As a final point, I also tested FIFOs and (unix domain) sockets.
FIFOs pass the test, sockets do not.
Regards,
Henri
