Cool, thanks.

I saw that you didn't add a license to the new files in libbb.
Can we put them under LGPLv2.1 or later?

I will add http://www.gnu.org/copyleft/lesser.txt as docs/lesser.txt as
several parts of lib*/ are under LGPLv2.1 or later.

PS:
The stat4 patch seems to add to the size a bit with gcc >= 4.1 in contrast
to the other patches so i'm hesitating to apply it for now..
