Indeed, it works for me too. Apparently it was the
'using namespace gnulib_system_namespace;' that collided with
'using gnulib::open;'.
But there's a big caveat: I don't know whether including system
headers inside a namespace
namespace gnulib_system_namespace {
#include <fcntl.h>
}
is portable or not. There are several ways in which this can fail:
- system headers that don't support this,
- system headers that are included by 3rd-party library headers.
Until you have made a large-scale test of this approach, on an entire package,
I would not recommend it.
