Hi Bob, sorry for the delay.

Which patch are you referring to exactly?

How does this later patch of mine fares?


Caveat: it works for GNU make only, and it's *really ugly*.  So ugly that I 
feel like applying it to automake proper.

"Again" is not the correct word here -- automake, either patched or not,
has *never* been able to run arbitrarily large test suites.  Still, recent
changes might have unintentionally reduced the maximal "testsuite size"
automake is able to handle, and we'd want to fix that.  How "big" is the
testsuite you are referring to concretely?

Anyway, for the moment, I've applied the patch (available from the link above)
that introduces a testcase for this automake limitation.  Better to keep the
issue exposed.

The exact version of the applied patch is attached, for reference.
