[Bug c/34800] New: Compile failure with --combine and a union with an anonymous struct

[alexandre dot nunes at gmail dot com]

$ cat pqp.c
typedef union {
    struct
    {
      unsigned char d;
    };
    unsigned char a, b;
} test_type;

extern test_type whatever;

$ gcc -c pqp.c
$ gcc --combine -c pqp.c pqp.c
pqp.c:9: error: conflicting types for ‘whatever’
pqp.c:9: error: previous declaration of ‘whatever’ was here


This seems like a more strict case of bug 28706 or something.
