See "Static pattern rules" in make.info. I think I needed it because
I couldn't work out an implicit rule which didn't spit warnings
and behave correctly at the same time when running make.

Hmmm... yes. That is a copy&paste. You don't need it for rtf files,
but I believe the problem I had was with %.txt, when there were
files with the same name in different directories (evil VPATH).

I thought we were requiring GNU make. Does Solaris use a version
of GNU make which doesn't support this? At the moment I wrote
that the only solution I could think of was writting a sed script
to match exact filenames with full path, but desisted when I saw
that entry in the manual.
