[Bug objc/20574] New: [4.1 Regression] werid error message after a parse error

["pinskia at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Take the following code:
@implementation A
+B
+C {} 
 @end 

With 4.0, we got:
t.m: In function ?+[A B]?:
t.m:3: error: syntax error before ?+? token

But with 4.1 we get:
t.m: In function ?+[A B]?:
t.m:3: error: expected ?{? before ?+? token
t.m: At top level:
t.m:3: error: redefinition of parameter ?self?
t.m:3: error: previous definition of ?self? was here
t.m:3: error: redefinition of parameter ?_cmd?
t.m:3: error: previous definition of ?_cmd? was here

The error messages about self and _cmd are not really needed (yes they are correct really but we should 
be able to do better with error recovery)
