For example, if the people who git would blame for adding ostensibly
GPL code to an LGPL library can confirm that it's okay for them to
have done so. It's possible I am one of the culprits here although
I've checked and I don't think so. Any code I may have moved would
originally have been written by Zoltan (e.g. goal_path stuff, which
may have got to mdbcomp via the browser directory).

Ok. Sounds like even more reasons to move things over in a piecemeal fashion.
Perhaps it is worth remembering at this point that there is probably
very little demand for people to distribute closed source binaries
with debugging enabled.
