He also said he needed to determine this from "outside the Cygwin 
environment" and I would think that cygpath is inside the Cygwin 
environment. Think about it. You're in cmd.exe and you want to tell 
where Cygwin is installed. How can you execute cygpath without knowing 
where cygpath is? The only way that would work is if Cygwin's bin path 
is already in PATH and this is not set by default when Cygwin is installed.

Personally I vote for a simple base like registry variable that plainly 
states where Cygwin was installed. It seems to me to make the most sense 
to have one globally accessible place where you can find Cygwin's 
installation path and then you can take it from there. Relying on 
anything within Cygwin's installation path presupposes that the person 
knows Cygwin's installation path! But this is just my opinion...
