o	(personal hobby horse)
		Re-do (cleanroom) any significant work done on
		the GNU toolchain so that it can be merged
		back in to the main GNU sources and base the
		cross compilers on that.

At any time, critical bug fixes needed for NetBSD to operate correctly
may need to be made to the toolchain; therefore, the sources for the
toolchain used to build a NetBSD release (either native, or cross)
should come from the NetBSD source tree.
