[other/80803] libgo

[Nathan Sidwell <nathan at acm dot org>]

Bill,
the revision you converged on is, as Ian, says, just moving some 
interface around.  That was needed to fix obj-c++.

This diff is the combination of that patch and its logical predecessor. 
Does reverting this diff get you back to normalcy?
