A fix for these failures (which I've only encountered when running the
automake testsuite with Linux -> MinGW cross compilers) should have
been applied to the testsuite-work branch some time ago (see commit
`v1.11-871-geb147a1', "lex tests: avoid spurious failures when LEXLIB
isn't found").

Ah, a failure I've introduced in 'maint' with commit `v1.11-360-ga370e2f'
"tests: fix spurious failure of txinfo21.test on FreeBSD".  It is due
to a limitation of the `is_newest' subroutine I hadn't thought about
(i.e., it doesn't work as expected on directories).  Should we hack
around this, or try to fix the `is_newest' subroutine instead?  I think
fixing `is_newest' is the best route. Anyway, I'll be AFK until tomorrow,
but then I'll give it a try (unless someone wants to beat me ;-)
