--- Comment #7 from Paul Romanyszyn pgr@arcelectronicsinc.com 2008-03-12 19:50:12 --- You are not bisecting correctly paul@paul-semipron:~/Git/wine-git$ git-bisect start paul@paul-semipron:~/Git/wine-git$ git-bisect bad wine-0.9.21 paul@paul-semipron:~/Git/wine-git$ git-bisect good wine-0.9.20 Bisecting: 202 revisions left to test after this fatal: Untracked working tree file 'dlls/winex11.drv/dce.c' would be overwritten by merge. Look at http://wiki.winehq.org/ReverseRegressionTesting for more info. But because of the error you need to try this git-clean -d git-checkout -f or the Step 0.
Note git-clean -d will wipe any thing you have in the git directory so I saved my compile script in new directory ../tools
