--- Comment #2 from Tim Shen <timshen at gcc dot gnu.org> ---
The default regex style is ECMAScript.
I didn't find any syntax that start with "(?s" in ECMA-262. Boost, however,
supports many extensions in its basic_regex_parser<>::parse_perl_extension()
function(probably for Perl style, I'm not sure), some of which are not included
in ECMAScript.
Following ECMA-262, we only support "(?=" "(?!" and "(?:".
