Not implemented in the operating system.  No.  Implemented in the
utilities.  Yes.  The utilities implement this functionality on
operating systems which implement that functionality.

You did not say but since you are using Cygwin you are probably
running on MS-Windows.  Cygwin is a port of GNU Project software to
MS-Windows.

The Cygwin software port mostly emulates the features of GNU and
UNIX-like systems.  But as the colloquial expression goes, you can't
make a silk purse out of a sow's ear.  You are still using MS-Windows
even in the wrapping of the Cygwin environment.  MS-Windows does not
to my knowledge support FIFOs.  (Although I don't really use the
systems much and my information there is limited.)  Therefore the GNU
utilities from the GNU operating system ported MS-Windows can't do
anything about it.  You would need to get support for named pipes
(FIFOs) in the operating system before application software can use
them.

Good Luck,
