That would be my preference. I haven't used C++ seriously in a while,
but I definitely remember that having a using in a global namespace is
a problem waiting to happen. So the codegen/unordered_set.h header
would go something like
#if foo
#include
#else if
#include
#endif
namespace nv50_ir {
#if foo
using a
#else if bar
using b
#else
crazy-class
#endif
}
Does that make sense to you?
