Constructions like those found in the shadow headers *are* fragile.
The good news is that it should be quite easy to add a compiler 
extension something like

  namespace __global_namespace__ { ... }

where everything in the brackets is treated as if it occurred
at the top level, no matter how deeply nested the declaration
occurs.  Given that and ``extern "C++" {}'', much of the fragility 
of the shadow headers could disappear.
