True.  I haven't been able to dig up an official reference to <regex> in
the GCC documentation until GCC 4.9.

I too get a failure in "runIntegrationTests".  The direct cause of the
failure is line 123 of runIntegrationTest.cpp,

I don't know what regular expression this is supposed to match.

And as for grammars, you can select those--options being Perl 5, basic,
