One of my larger pending todo items for aboriginal is fishing the last =20 gplv2 release out of gcc git the same way I did for binutils. (In =20 theory, this should give me armv7l support. In practice, the mpfr and =20 gmp split complicates matters...) If somebody wanted to come up with an armv4-eabi patch, I'd happily =20 include it. Or just give me rather a lot of hints on what would be =20 involved, since I'm not much of an arm assembly programmer... Rob=
