While I'm rusty on make these days, ISTM that there is something wrong
with the makefile, as io.h should not be a target. Headers are included
in source files for targets (xx.o), not built separately. It is then
unsurprising that there is no rule for no build.

Listing io.h as a dependency, either on the target line, or as a
separate dependency:

Timer-5D-DD-0715.o: io.h

will tell make to rebuild the target if io.h has changed, but only an
erroneous placement of io.h as a target ought to create your current
problem ... in theory.

Even if you use suffix rules, .h should only appear on the right of the

colon.

If you would post the makefile, it may be possible to spot the problem.

That may be just a display artifact, escaping perhaps.

Is there really only one makefile?

An instance of make is being run - it announced itself in the error
message. For completeness, is it gnu make or some lesser imitation?

Has that been upgraded recently? (With a buggy version)

P.S. CCing as last two posts to other lists didn't make it to list.
