qi conflicts with x3

[mikhail.strelnikov@…]

Would be nice if this compiled:

    #include <boost/spirit/home/x3.hpp>
    #include <boost/spirit/include/qi.hpp>
    int main() {}

(now it fails with error: 'kleene' does not name a type)

I have the same problem when trying this:

#include <boost/spirit/home/karma.hpp>
#include <boost/spirit/home/x3.hpp>

Errors out with:

boost/spirit/home/x3/support/numeric_utils/extract_real.hpp(27): note: see declaration of 'boost::spirit::x3'

Similar error if I flip the order of includes.

As I mentioned at ​https://github.com/boostorg/spirit/issues/257

The reason is SPIRIT_SIGN_MAR_11_2009_0734PM is already defined in:

boost\spirit\home\x3\support\numeric_utils\sign.hpp

which triggers the include guard of:

boost\spirit\home\support\detail\sign.hpp
