In a previous installation I ran into this problem (but just with svn). In that case, I identified a missing DLL - However, I cannot remember which one.

I have done a comparison of what is in /lib on both the broken and a correctly functioniong Cygwin installion and have found no missing DLLs.
Copying this DLL (cygz.dll) off another cygwin installation seems to work OK.
 
Not sure why it is missing?

Executables Do Not Run

I have observered a problem in a migration I have just done where executables such as ssh.exe, sshd.exe and svn.exe do not run but simply exit with no output when you attempt to run them.

In a previous installation I ran into this problem (but just with svn). In that case, I identified a missing DLL, C:/cygwin/bin/cygz.dll.

Copying this DLL (cygz.dll) off another cygwin installation seems to work OK.

Not sure why it is missing?

Was able to diagnose the problem using MS System Internals tool FileMon - as follows:
