* Extend __has_include grammar for complex conditional expressions The logic handling __has_include erroneously assumed it would always be the last expression on a line. This code fixes that by extending the grammar to only consume the __has_include() itself, and count parentheses as necessary to find the correct input range. Also add some unit tests to cover the error in the future. * While I'm at it, a couple of small cleanups 1) Remove unneeded header 2) The wrong BOOST_SPIRIT_DEBUG_TRACE_RULE was commented out
