--- Comment #9 from Paul Romanyszyn pgr@arcelectronicsinc.com 2009-10-23 00:52:32 --- I had what I thought was regression a while back. What I think but could not prove was when the16 bit dll directory is moved some of generated files not tracked by git get left behind when you doing the git checkout or bisect. As a result you now have old code or dll's left in the build tree. I never found a git command to fix it. I think I just deleted everything in the wine-git directory except for the .git and then checked the tree back out.
