Ok, but that just means the testsuite has to be changed in sync with  
changes to the compiler - like with many other tests (ie, like those  
including type error messages).

Can you fix that or anybody else who uses that platform?  (I am making  
an effort to hunt down all Mac OS X breakages that I find.  For every  
platform, we need somebody to do that.)
