I just tried to compile Suse Linux package yast2-perl-bindings-2.14.0-11
with the new GNU C++ compiler version 3.2 snapshot 20061216.

Strange - is there a possible typo on the last date ?
I found snapshot 4.3-20061216 going wrong, so if the
last date is correct, we can reduce the interval
to 20061202 to 20061216.

This is obviously caused by the tuple changes.
I am trying to find a simple fix for this bug.

unsigned foo(unsigned x) {
return __builtin_constant_p(x) ? 0 : f(x);

Note that this small testcase of mine is destilled from FreeBSD's system
header. This bug causes bootstrap failure on all FreeBSD systems I am
aware of (which is why Andrew labeled this a blocker, I assume).
