Since I upgraded from BBv1 to BBv2 very recently, I discovered some 
missing features in gcc toolkit that were present in v1, but lacking in 
v2. Here's the patch against cvs HEAD for some of those. I was unable to 
find patch submission guidelines on the site, so it's standard unidiff 
with 2-line context. Hope it's correct.
