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 ("[{]") ..
|
|
|
|

|
|
|
|
* bin/automake.in (substitute_ac_subst_variables): Escape the
|
|
occurrence of '{' character.
