We talked about this on the bsd-port mailing list. It may be due to
new error checks in GCC 4.2.
On Mac, even after those compile-time errors are fixed, GCC 4.2 does
not build a usable hotspot. After upgrading to Snow Leopard (10.6), I
had to back the gcc to 4.0 for building hotspot.

Hi Martin
I've just changed my Linux box to a x86_64 one, and my first build
of JDK 7 shows these errors:

What am I missing here? and, do you have any private patches to share?
Thanks
