You're on a 64 bit system and the cluster command only exists as 64 bit
application in the 64 bit system32 directory.
Due to the Windows file redirection for 32 bit processes, if you cd into
/cygdrive/c/Windows/System32, you're actually in
/cygdrive/c/Windows/SysWOW64.  What you want to do is to cd into
/cygdrive/c/windows/Sysnative.  You'll find the cluster command there.

Note that this is not a Cygwin problem, but one of the many weird
properties of 64 bit Windows OSes.  It would have been so much easier
for everyone if the directory containing the 64 bit applications and
DLLs would have been named /cygdrive/c/windows/System64, but here we
are.

See http://msdn.microsoft.com/en-us/library/aa384187%28VS.85%29.aspx
for details on the file system redirector.
