I've successfully built b31 with gcc 4.3.1 via IcedTea7:

./openjdk/build/linux-amd64/bin/java -version
java version "1.7.0_0"
IcedTea Runtime Environment (build 1.7.0_0-b31)
OpenJDK 64-Bit Server VM (build 1.7.0_0-b31, mixed mode)

Notably, we were able to drop a patch from IcedTea that removes the
-Werror flag because the gcc 4.3 problems have been fixed:
