If you kept the original source around, you can create a patch and apply
it (perhaps by hand, at this point).  Unless your changes were in the few
areas of active development, most changes should be easily forward-ported
to newer Cygwin code - most of it hasn't changed *that* much.  FYI, if you
installed the source package through setup.exe, the original tarball is
probably still in the setup cache directory.

Yes, you can.  If you want to be completely safe, rename the old
cygwin1.dll to, say, old-cygwin1.dll (I have a few on my system, no
problems yet).
