Switching the "known to fail" versions around to make this bug appear
on the 4.5.0 regression list... maybe this will work.

AFAIK, P3 regressions cannot be "enhancement", setting
severity to "normal".

Works with 3.4:

$ cat > tmp.c
unsigned char foo(unsigned char a)
{
  a >> 2;
  return a;
}
$ gcc-3.4 -S -O3 -Wall tmp.c
tmp.c: In function `foo':
tmp.c:3: warning: statement with no effect
