It turns out that the problem was caused by my mistake in including an
object file in the SOURCES line where I should have included the
corresponding C source file.  But I still think that such a mistake
should result in an error message from automake, not one from Perl.

The following shell script creates a Makefile.am which exhibits the
problem.  I am not really sure what the appropriate test should be as
it might be difficult to differentiate a bad exit status from Perl from
a bad exit status from automake.
