System::Windows::Forms; // won't compile

Error 1 error C3083: 'Window': the symbol to the left of a '::' must
be a type
Error 2 error C2039: 'Forms' : is not a member of 'System'
Error 3 error C2871: 'Forms' : a namespace with this name does not
exist
There are other "using namespace" declarations immediately above this
one that do compile.
