OK, after talking to the owner of the OpenIndiana machine I understand
the issues more.

He has installed GNU make on that VM/Zone anyway, but the fundamental
issue is that Solaris make does not do transitive evaluation of
pattern rules.

The solution is to have a rule rather than separate and .c.o rules.

In an effort to have the resulting Makefile work in more situations I
will make that change soon and put comments in the Makefile to help
those who want to do more complex things. (I will also test that it
works on my OpenIndiana VM.)
