Attached is the beginning of a rebase utility. It is modeled after the
MS one:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/tools/perfutil_2z39.asp
So far I have only implemented the -b and -d options.
If a stand-alone utility is still deemed useful (as opposed to integrating
the functionality directly into setup.exe), then I will "GNU-ize", clean
up, and submit it to cygwin-patches for consideration.
