Since 4.7 we have need_64bit_hwint=yes for the target the bug was reported
against.
But I'm confused. Do we want two warnings here?
3.3.6 and 3.4.6 say:
/space/rguenther/install/gcc-3.3.6/bin/gcc -S -std=c99 t.c
t.c:10:13: warning: integer constant is so large that it is unsigned
t.c: In function `f':
t.c:10: warning: integer overflow in expression
while since 4.0.0 we say
t.c:10:13: warning: integer constant is so large that it is unsigned
I don't think we anywhere have a 'integer overflow in expression' warning
(not by default at least) that triggers during optimization.
So - is 4.7 fixed (because hwint 64 is default)? I didn't really check
hwint32 builds of 4.x.

I guess we can close this for 4.7+ where we have always 64-bit HWINTs on i686.
