That's great to know, thanks!

Given the fact that lenny is supposed to release near the end of this
year, and that the toolchain is going to be frozen sometime next month,
integrating your work into lenny is not going to be possible anymore.
Therefore, I think it's best if we just wait until your work is merged
upstream and trickles into Debian, but look out for any incompatibility
issues that might arise.
A heads-up when you're doing merges into the toolchain's respective
upstreams would be appreciated.

Right, that makes sense
