Thanks for checking. But let me note that the Makefile is meant for
development - it is part of the internals of the package, similar to
compat-macs.el or the compat--* functions. It is not meant to build the
package. Emacs packages like Compat can be build as usual, like any
other Emacs package which does not provide a Makefile.
