Confirmed, this is a very very recent regression.
It worked with 20050225 but not with 20050301. Note my 20050225 was right

and nothing much has changed on the branch yet.
This only happens on the mainline and not on the 4.0.0 branch.
And it looks like it is caused by:

* config/rs6000/rs6000.c (EASY_VECTOR_15): Remove.
(EASY_VECTOR_15_ADD_SELF): Remove.
A simple testcase would be:
long foo(long word)
{
return word + 2147483647L;
}
