I would just add that if you (the OP) are unable to solve the problem by 
rebasing, then you should make a report to the Cygwin mailing list 
following the guidelines at

  http://cygwin.com/problems.html ,

especially the part about attaching cygcheck output.  It could be that 
you have too many DLLs installed for 32-bit Cygwin.  (If it's possible 
for you to switch to 64-bit Cygwin, your rebase problems will go away.)

This is not an Emacs bug.

Ken
