The definitive answer is don't use quotes in your Win32 path.  They're
not needed by Win32 and they break Cygwin.

That would be because in the five years I've been on this list, you're
the first person with the problem.  I would say the risk is pretty low
so spending time thinking about a fix for anyone is a waste.  The answer
is, don't quote the paths in the Win32 environment.

Why did you reinvent the wheel?  Why not just use the which-2.12.tar.gz
file provided on any gnu mirror?
