Assembler errors building gcc 3.1 on OpenBSD 3.1

["Jarvis, Michael" <mjarvis@pacebutler.com>]

I'm attempting to build gcc 3.1 on a machine running OpenBSD 3.1.

I am building in a separate gcc-obj directory, and I configure with:

../gcc-3.1/configure \
        --prefix=/home/gcc-3.1 \
        --enable-languages=c++ \
        --enable-version-specific-runtime-libs \
        && make bootstrap

Everything goes fine until I receive the message below.  I've tried just
about everything I can think of but I cannot get gcc 3.1 to build
successfully.  Any assistance would be appreciated.
