I know and I consider it broken.  This is what Roland was worried
about back in August when libc's view of some headers was made
different from the normal-program view.  A test case has to be treated
as if it were a normal program.

I know how to fix the problem, but the code changes would be so
extensive I don't think Uli wants them in 2.1.
