As Andrew Pinski pointed out, we suppress ICEs after regular errors.
You have to configure the compiler with --enable-checking to see the real ICE.

To clarify, GCC 3.4.x miscompiles GCC 4.4 when not being bootstrapped. A
normal bootstrap won't show this failure, but a cross build or
--disable-bootstrap will.

This failure comes up whenever GCC 3.4.x is used to build GCC 4.4 on Windows.
I'm not sure if it affects any non-Windows targets.

Building for a target of win64 on cygwin results in an ICE while building the
