Ian Taylor - Dec. 3, 2011, 2:17 a.m.
I have updated the libgo library to the weekly.2011-11-02 release of the
master library.  The only changes in this patch are to switch from using
the type os.Error to the new predeclared type error, and to add a new
errors package providing a couple of convenience functions.  This causes
mechanical changes to over 450 files in the library.  I have not
included the complete diffs in this e-mail message; they are available
from SVN or from the master library.  I have only included the diffs to
files outside the Go library proper.  Bootstrapped and ran Go testsuite
on x86_64-unknown-linux-gnu.  Committed to mainline.

Ian
