1734	BOOST_STATIC_WARNING can't be passed a dependent expression	Dave Abrahams	Robert Ramey	"This breaks Boost.Serialization on conforming compilers like Intel/Linux.

{{{
#!cpp
#include ""boost/static_warning.hpp""

template <class T>
int f()
{
    BOOST_STATIC_WARNING(T::value);
    return 0;
}       

struct A{ enum { value = true }; };

int x = f<A>(); 
}}}

The problem is that there's a missing {{{typename}}} in the code generated by the macro:

{{{
#!cpp
template <class T>
int f()
{
    struct STATIC_WARNING7 { ::boost::static_warning_impl<(bool)( T::value )> ::type* p; void f() { delete p; } };
    // ---------------------^ HERE
    return 0;
}       
}}}

I think there are tricks that can help you get around this requirement (ask Daniel Wallin what he did in the Parameter library), but in the meantime BOOST_STATIC_WARNING should at least be made into a no-op for Intel C++.  That is enough to get the library working on one additional platform and might even be an acceptable change for 1.35.0
