I noticed a very old branch called "flameeyes" in sandbox.git. This branch appears to have some autotools-related changes that flameeyes wrote back in 2009. I reviewed the commits, and It looks like most of these changes have either been merged or implemented in slightly different ways. The only exception I found was 6a86cbbfdb355384435ce276f532cbc36a6b7f7a, which makes configure error out if an "sighandler" type cannot be found. I doubt this check actually fails on any system we care about. Given that flameeyes is retired and there's nothing particularly useful on this branch, we should probably drop it.
makes no diff to me either way
I dropped the branch.
