This PR is already closed.

Since its first revision (install.1,v 1.7 and install.c,v 1.16 they
were incompatible).  Later on, in rev. 1.26, it was made a no-op,
just to support "INSTALL=install -C" in /etc/make.conf.

OpenBSD merged these changes and since then they still have them

There are two ways to proceed:

1.  Rename COPY to INSTALL_COPY (that was my plan), optionally giving
    it by default an empty value.  This shouldn't harm third-party
    makefiles as -c is now an effective no-op.  But this would make
    us even more compatible with OpenBSD that has:

: INSTALL_COPY    The old usage of this flag is obsolescent since install(1)
:                 now copies by default.  However, it can also be used to
:                 specify that a file not be copied unless it is different
:                 (via the -p option).  See install(1) for details.  This
:                 is to be used when building our own install script so
:                 that the entire system can either be installed with copies,
:                 or copy-if-different using a single knob. [-c]

2.  Make again -C an allowed (ignored) option in the -d case.  This would
    make us again incompatible with OpenBSD.

I do not have a technical problem doing either, I'd just like to know
what do others think about this.
