RE: Strongtalk: planning a way forward

Hi,

Yes, the gcc-prunedtree branch in the repository is based on prunedtree's
contributions.  The code has been reviewed, and it now compiles under VC++
2005 Express, but it doesn't run yet (his original contribution was for VS
6).

If another line of work includes that stuff and has gotten farther, feel
free to integrate and or delete that branch.
