Trying to figure out what is wrong in a colleague's Cygwin setup

[David Karr]

(I replied with this earlier directly to someone who I didn't realize had
only replied to me.)

I do have a couple other clues that I've noticed while continuing to debug
this.

This person also has "git bash" installed, which is certainly similar to
Cygwin, but not quite the same.  In his gitbash shell, he does not get this
error.

If it matters, here is the "uname -a" output (hostname elided):

    CYGWIN_NT-10.0-22000 ... 3.4.6-1.x86_64 2023-02-14 13:23 UTC x86_64
Cygwin

If it matters, here is the same from his gitbash shell:

    MINGW64_NT-10.0-22000 ... 3.1.7-340.x86_64 2021-03-26 22:17 UTC x86_64
Msys

He is running Windows 11 (as I am).

What else can I try to narrow this down?
