Definitely the latter and probably the former.  :-)

I absolutely agree, but I am concerned that those alternative
installation means might be the source of the issue.

Have you reported this to Cygwin as a bug?  Their response to the
fork issue was extraordinarily fast.

By the way, when you report that possible cat bug to Cygwin, I am sure they will
insist you use standard means (e.g., setup.exe) to install Cygwin to
remove any uncertainty about whether your non-standard installation is
the cause of the issue. And they will also probably insist you
demonstrate the issue for the Microsoft version of Windows since Wine
currently has an uncertain reputation (rightly or wrongly but we
cannot say anything about that until the standard Cygwin method of
installation works) concerning its ability to run Cygwin.

You may have really found a valid Cygwin bug for their version of cat.
But I _know_ the MSYS version of cat works fine on recent Wine just
like the rest of the GNU toolchain used for building software so if
the MSYS and Cygwin GNU toolchain code bases have not diverged too
much it should be straightforward (and probably quite fast, if the
fork bugfix speed is anything to go by) for the Cygwin developers to
fix the issue if you prove it actually exists with a standard Cygwin
installation on Microsoft Windows.
