nested unnamed structs/unions broken?

[steve at chelsio dot com (Steve Watt)]

The following code:

 - - - 8< - - -

#include <stdio.h>

union optid {
    unsigned int opcode_tid;
    struct {
        unsigned int opcode:8;
        unsigned int tid:24; 
    };
};

struct cpl_msg {
    union optid;
    int item1;
};

int main() {
    struct cpl_msg x;
    int opcode;
    int tid;

    x.opcode_tid = 0x000102da;

    printf("opcode %x tid %x\n", x.opcode, x.tid);

    exit(0);
}


 - - - >8 - - -

compiles and works with GCC 2.96 (ugh) and 3.2.2[FreeBSD] 20030205,
but with 3.4-20030819 (experimental), it fails during compilation:

     tpun.c:12: warning: declaration does not declare anything
     tpun.c: In function `main':

     tpun.c:21: error: structure has no member named `opcode_tid'
     tpun.c:23: error: structure has no member named `opcode'
     tpun.c:23: error: structure has no member named `tid'


I don't have a 3.3 handy to check against.  This feels like a bug
in 3.4, but I don't spot anything in the GCC Bugzilla that hints
towards it.

Thx,
