In our project we like the Cygwin-Setup tool so much that we use it for our own files too.
Adding our archives to our setup.ini was easy enough and almost everything worked as expected.
But then a certain tool didn't work and we found that dll-files that were unpacked by the
Cygwin-installer didn't match the files in the archive.
The problem seems to be dll-specific. Other filetypes are not modified.
Cygwin's rebasing of DLLs does modify the files (slightly).
Others can probably detail the exact nature of what changes,
and perhaps the comparison tool can be refined to ignore that
as a difference.
the change is on ImageBase address
$ objdump -x /usr/bin/cygglpk-40.dll |grep ImageBase
So, if the OP compared output of objdump ignoring the ImageBase difference,
would that be able to indicate that the DLL is "the same" for his purposes
of knowing whether an installation is equivalent in terms of versions,
