   4 Subject: [PATCH] automake: port to Perl 5.22 and later
   5
   6 Without this change, Perl 5.22 complains "Unescaped left brace in
   7 regex is deprecated" and this is planned to become a hard error in
   8 Perl 5.26.  See:
   9 http://search.cpan.org/dist/perl-5.22.0/pod/perldelta.pod#A_literal_%22{%22_should_now_be_escaped_in_a_pattern
  10 * bin/automake.in (substitute_ac_subst_variables): Escape left brace.
