Message:

Empty expressions, and empty alternatives are now
allowed when using the Perl regular expression syntax. This change has
been added for Perl compatibility, when the new [syntax_option_type]
['no_empty_expressions] is set then the old behaviour is preserved and
empty expressions are prohibited. This is issue
[@​https://svn.boost.org/trac/boost/ticket/1081 #1081].

Fixes #1081.
