I have tried to install perl 5.26.1 on my local machine.  But I wasn't
able to reproduce this bug.  Here are the commands I have executed from
the Automake git repository:

   $ PERL=/path/to/local/perl ./bootstrap
   $ ./configure PERL=/path/to/local/perl
   $ make

Can you provide a recipe to help me reproduce it?

Sorry for the delay.
