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.
