Thanks for the bug report.

That looks like heirloom-make uses its own internal rule for baz5.c and
for foo5.c.  That would be problematic because ylwrap is not used, and
other problems.  With a non-flex lex you'd see more test failures I
suppose.

Hmm.  Actually, one can see that first, the internal rule is used, but
then our rule is also used afterwards (the lines matching LEX.*5.c).

Is this the only test failure with heirloom-make?  I'd expect quite a
few more, but I'm guessing we have most of those with a
  required=GNUmake

line.

Where can I get this heirloom-make?  Is there a Debian package for it?
I'm not bound to bother much with this issue because no user is forced
to pain herself with heirloom-make (and even Solaris make is better).

I'm guessing this has to do with chains of inference rules not being
detected or so.
