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.
