Running bc by itself gave the same error message.
Just in case that bc was not part of cygwin, I deleted it and reran the
install. It did not seem to have bc listed as a component to install.
My PATH is now:
/usr/local/bin:/usr/bin:/cygdrive/c/Windows/system32:/cygdrive/c/Windows:/cygdrive/c/Windows/System32/Wbem:/cygdrive/c/Windows/System32/WindowsPowerShell/v1.0:/cygdrive/c/Windows/System32/OpenSSH:/cygdrive/c/Program
Files/NVIDIA Corporation/NVIDIA NvDLISR:/cygdrive/c/Program Files
(x86)/Emacs/i686/bin:.:$HOME/bin:/cygdrive/c/usr/bin:/cygdrive/c/Users/clayt/AppData/Local/Microsoft/WindowsApps
If bc is not in cygwin, what should I use to get a version for Windows?
Or do I need to roll my own?

Cygwin's bc does not depend on this library and it would not give you
this error message either. I suggest you try "/usr/bin/bc" from a
Cygwin shell and then think about what you want to have your PATH look
like.
I wonder which setup program that was, and how your environment is set
up?
That message is from a native Windows port of bc, installed under/by
Mingw/64, Msys/2, Chocolatey or some other native Windows port
installer that does not handle library dependencies. You would have to
install that environment's readline library using their setup program.
If you have installed Cygwin, you must start it using (perhaps some
minor variation of) the provided shortcuts, command files, or scripts,
and ensure the Cygwin path is set with Cygwin /usr/bin/ near the
start, possibly preceded by your own local script directory/-ies: e.g.
$HOME/bin:/usr/local/bin:/usr/bin
