Uninitialized value in string ...

[Szekely Izabella]

Hello!

I use automake 1.7.1, on Read Hat Linux 7.3.
When I run automake, I get I have following error
Use of uninitialized value in string eq at /usr/bin/automake line 5149,
<GEN0> line 2.
Use of uninitialized value in string eq at /usr/bin/automake line 5149,

Does anyone know what the below messages are all about?  Line 5149 is
like this:


while ($_ = $tracefh->getline)
    {
      chomp;
      my ($here, @args) = split /::/;
      my $macro = $args[0];

      # Alphabetical ordering please.
      if ($macro eq 'AC_CANONICAL_HOST') <==== 5149
        {
          if (! $seen_canonical)
            {
              $seen_canonical = AC_CANONICAL_HOST;
              $canonical_location = $here;
            };
        }
