Does that error go away if you remove the parallel-tests option?

The list of test logs in GraphicsMagick has a length of 24132 over here,
which isn't surprising to exceed the AIX 4.3.3 limit (see
<>).  But the old test
suite driver should have had the same problem, as it also expands
$(TESTS) which isn't much shorter (23348 here).

So far we do not know of a portable way (both to different operating
systems and to different make implementations) to work around this limit
in a general way.  With many Automake constructs, you can use multiple
special variables (see the "Length Limitations" node in the manual), but
such a solution has not been implemented in Automake for tests yet.

You should be able to work around it by splitting tests in pieces,
and running things piecewise only for now; assuming the *_TESTS
variables are all nonempty:


        $(MAKE) $(AM_MAKEFLAGS) check-TESTS \
                TESTS='$(WAND_TESTS)' TEST_SUITE_LOG=test-suite-wand.log


I agree that it's a bit of a kludge (and I haven't tested it yet).
