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