--- Comment #16 from Mikael Pettersson <mikpe at it dot uu.se> 2011-06-29 07:40:20 UTC --- 4.2.4 (lightly patched) and 4.3.6 (heavily patched) both bootstrap fine with gnat and rebuild themselves without problems. I'm going to rebuild 4.3.6 with a much smaller patch kit first, then move on to 4.4.6.
