Subject: [PATCH 2/6] UML - Fix an IPV6 libc vs kernel symbol clash
Date: Thursday, August 2, 2007 - 5:04 pm

On some systems, with IPV6 configured, there is a clash between the
kernel's in6addr_any and the one in libc.

This is handled in the usual (gross) way of defining the kernel symbol
out of the way on the gcc command line.
