+Subject: [PATCH] bin/automake: escape '{' in regexp pattern
+
+Based on perlre(1) documentation:
+.. in Perl v5.26, literal uses of a curly bracket will be required
+to be escaped, say by preceding them with a backslash ("\{" ) or
+enclosing them within square brackets ("[{]") ..
+
+References:
+https://bugzilla.redhat.com/1239379
+
+* bin/automake.in (substitute_ac_subst_variables): Escape the
+occurrence of '{' character.
