Objective-C compiler broken

[Nicola Pero]

Hi 

the objective-C compiler in the latest snapshot (and all previous
snapshots I know of) is broken (the runtime library is in great shape
instead). 

Basically, I can't compile any objective-C code.  Finding out why is
pretty difficult for me, anyway I spent a couple of hours to build a very
simple test case showing an example in which the latest snapshot fails
while stable releases of gcc do a fine job. 

In attach there is a couple of tests which gcc-2.95.2 compiles fine while
the gcc snapshot 20000911 fails to compile.  Basically they show that the
compiler can't compile methods returning `oneway void' any longer. 

Please would you add these two tests to the objc testsuite (and of course
fix them before next release). 

I'll try submitting more test cases if I can, thanks for the great work.
