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

[pinskia 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)
