egcs and bitfields

I think the problem with your previous report was that it was hard to
understand. I tried to come up with a program that demonstrates your
problem, and I got

struct baz { unsigned int a:2, b:4, c:32;} y;

void foo()
{
  y.c = 0x56789;
}

int main()
{
  unsigned int  *b;
  bzero(&y,sizeof(y));
  foo();
  b=&y;
  printf("%x %x\n",b[0],b[1]);
}

Is this the case you are talking about? Now, you claim that the SysV
ABI requires y.c to be at offset 4, right? (this is a claim I can't
verify since I don't have that specification)

Anyway, when I run the program on i586-pc-linux-gnu, with
egcs-2.93.11, I get as output

0 56789

>From your explanation, I understand that this result is
ABI-compliant. So where is the problem?
