Ah, ok. A couple of comments. First, a bug I introduced by giving a
non-complete example: Some `make' implementations will not allow you to
override a macro on the command line iff it is also set in the Makefile.
With `TESTS', that is the case in your script. Portable would be
TESTS='...' make -e check
but `make -e' has its share of problems, too, depending on your
environment (same issue with the other variables, of course). Another
point where Autotest is more flexible.
Furthermore, you write
| check_PROGRAMS=$(MAKEFLAGS='' make -s print_check_PROGRAMS)
which I assume you need to avoid clutter in the output. I know many
systems where it is very useful to override the `make' command used,
so $MAKE would probably be better here and elsewhere in the script
(unless that interferes with clutter in the output), e.g. to be able
to use a make that allows macro override on the command line.
Then, a comment to the Makefile.am: you don't need the lines
| srcdir = @srcdir@
| VPATH = @VPATH@
| SUBDIRS =
automake will take care of that by itself.

The next Autoconf release should have a decently usable version of it.
