Cygwin rebase

If you got errors like fork() or stack exceptions when starting cygwin, try rebase.

Here the steps to run rebase:
0. Close all cygwin app/terminal
1. start a Windows cmd terminal console (not cygwin terminal, this is very important)
2. #cd c:\cygwin\bin (where your cygwin binaries are installed)
3. #ash
4. #./rebaseall

Done!
