Hi Max, Sounds to me like you're using a very recent gcc. My policy has been to use a stodgy gcc, and let other folks use bleeding edge. Fedora/Ubuntu hackers are more likely to dogfood their gcc.... so check out the icedtea patch set.
I wish that Openjdk release engineering maintained buildability by a broad range of compilers through regular testing.
