I'm trying to get started with boost xpressive, but have problems with 
this simple attempt...

#pragma warning(disable:4180) // MSVC: qualifier applied to function 
type has no meaning; ignored
#pragma warning(disable:4224) // MSVC: nonstandard extension used : 
formal parameter 'value' was previously defined as a type
#pragma warning(disable:4996) // MSVC: 'std::transform' was declared 
deprecated

#include <boost/xpressive/xpressive_static.hpp>

void f()
{
     using namespace boost::xpressive;

     sregex rex = as_xpr('k');
}

...which gives these errors...
