Subject: Should cygwin's setup*.exe be signed using Sign Tool?

Running setup*.exe produces "Publisher: Unknown publisher", and it's doubtful that many people check the signature of the .exe file before running.  Even if they did, there's the problem that the signature comes from the same place.

Has Cygwin considered signing the installer using Sign Tool? More info:

I believe signing it this way would eliminate the "unknown publisher"; it would also protect the many people who don't follow the current signature-checking process.  This would create a strong barrier against code subversion after release.

The signed executable could also be signed using the current process, so you don't need to *eliminate* any capability.  I can't provide a patch to do this, obviously :-).
