[Bug objc/7098] ObjC front end doesn't understand attributes on method parameters

["dominiq at lps dot ens dot fr" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #7 from dominiq at lps dot ens dot fr  2008-09-19 18:32 -------
Although I know this is not the right way to fix pr34310 I have done the
following change to /usr/include/objc/Protocol.h:

--- /usr/include/objc/Protocol.h-orig   2008-09-19 17:16:42.000000000 +0200

 @end

and the number of failures has gone fom:

=== objc Summary for unix ===

# of expected passes            2896
# of unexpected failures        85
# of expected failures          7
# of unresolved testcases       74
# of unsupported tests          2

to

# of unexpected failures        9
# of expected failures          7
# of unresolved testcases       2
# of unsupported tests          2

Now the failures are

I have also done similar changes to

/System/Library/Frameworks/Foundation.framework/Headers/NSArray.h-mine
/System/Library/Frameworks/Foundation.framework/Headers/NSCoder.h-mine
/System/Library/Frameworks/Foundation.framework/Headers/NSDictionary.h-mine
/System/Library/Frameworks/Foundation.framework/Headers/NSObject.h-mine
/System/Library/Frameworks/Foundation.framework/Headers/NSRunLoop.h-mine
/System/Library/Frameworks/Foundation.framework/Headers/NSSet.h-mine
/System/Library/Frameworks/Foundation.framework/Headers/NSString.h-mine
/System/Library/Frameworks/Foundation.framework/Headers/NSURL.h-mine
/System/Library/Frameworks/Foundation.framework/Headers/NSURLHandle.h-mine

but all of them only fix objc.dg/headers.m because I have been unable to find
what to change in

/System/Library/Frameworks/Foundation.framework/Headers/NSPointerFunctions.h
