Hello Jim,

On a related note, it'd sure be nice if "make -j4 check" would run its
tests in parallel.  Especially on an SMP system, and/or when some
tests sleep for a few (interminable :-) seconds.

Of course, this might not be trivial, especially trying to keep
the resulting portable.  However, even if it means
I'd need to use a special option to generate a GNU-make-only, I'd happily use the result for day to day work.

IIRC, Akim Demaille posted a patch a while ago on an automake list for
this, GNU make-specific.  I don't recall how much work was left to do,
but on my list it's a bit on the far end.

The whole idea is to have one input file per test (say a .chk file) that produces a .log file. We can then benefit from the parallelism of make with implicit rules (exactly like for .c -> .o).

The file has slightly evolved since then but I can post an updated version if someone is interested.
