Ian Taylor - Jan. 13, 2012, 5:11 a.m.
I have committed a patch to libgo to update it to the weekly.2011-12-22
release.  As usual I am not including all the changes here, only the
ones to files which are specific to gccgo.  Bootstrapped and ran Go
testsuite on x86_64-unknown-linux-gnu.  Committed to mainline.

This also broke bootstrap on x86_64-unknown-linux-gnu (CentOS 5.5):

/vol/gcc/src/hg/trunk/local/libgo/go/net/fd_linux.go:40:46: error: reference to undefined identifier 'syscall.EPOLL_CLOEXEC'
