[Bug c++/35000] New: #include sometimes fails in namespaces

[mw268 at bath dot ac dot uk]

When including a system header in a namespace followed by another system header
seems to prevent declarations being recognized in the headers or some such.
Even happens when the headers are both the same.

Example code:

#ifndef APP_H
#define APP_H

namespace win
{
        #include <string>
}

#include <iostream>

#endif

This is working as designed.  Why are you doing #include inside a namespace
anyways?

I was using it to enclose windows.h in a namespace win to avoid potential
problems and ended up causing one. The reason I thought I was a bug was because
it works if the #include is before the namespace.

This way you make the compiler believe that all the functions
are in a namespace when the compiler that compiled these functions
into a .dll assumed that they are not. This can't work.
