[Bug objc/34033] New: compiler accepts invalid string concatenation

[tromey at gcc dot gnu dot org]

The code in c-lex.c that handles string concatenation allows weird,
and from what I can tell invalid, ObjC string concatentations.
In particular it allows any number of "@"s, and trailing "@"s.
E.g., it treats these as valid strings:

   "foo" @@@@@ "bar"
   @"foo" @@@@@
