Yes, that is exactly what I am doing, based on the following quote from
(automake-history)Recommendations for Tool Writers:

=2D-8<---------------cut here---------------start------------->8---
Finally, the tool should generate a dependency for each probe, instead
of each successful file open, in order to avoid the duplicated new
header bug.
=2D-8<---------------cut here---------------end--------------->8---

I probably misunderstood it.  I will re-read the chapter 2 and try
again.

I am still at least trying to stick to POSIX make, but will keep this as
an option, thank you. :)

There are only two hard things in Computer Science:
cache invalidation, naming things and off-by-one errors.
