I got these errors too, when trying to bootstrap gcc-4.8-20120909 on m68k-linux
using g++ 4.5.3 as the bootstrap compiler.

Works for me. I believe the problem is the overflow detection
in the new code.

Based on my testing, this was fixed by Lawrence's commit on
the 24th. It added double_int::sub_with_overflow and
double_int::neg_with_overflow to fix the problem.
