Do you really need to use the latest version of RCS offered by MSYS2?

Naturally, that's what I would recommend ;-)  I'm still using the
ported RCS available there for some very old repositories.

Nothing; those ports are native Windows ports and will work with a
native Windows Emacs without any problems.  They do for me.

Well, you have just bumped into one problem with MSYS2 solutions.  In
general, if you want to use MSYS2, you should have most or all of your
programs be MSYS2 builds, not MinGW (a.k.a. "native") builds.

OTOH, the ezwinports port of RCS should run from MSYS2 shells without
problems.
