This isn't too surprising.  Cygwin 1.7.* determines its root directory
from the location of cygwin1.dll.  If you move cygwin1.dll to directory
c:\foo\bin it will look for other required files in, e.g.,
c:\foo\usr\share and won't be able to find them.  ncurses/terminfo need
files in /usr/share so they won't work correctly.

If you are packaging the Cygwin DLL with with other stuff you will need
to investigate the Cygwin mount table and possibly provide an /etc/fstab
file or copy more files into the other directory.

Btw, looking at the above web site, it seems like you may not be complying with
the GPL since you don't seem to be providing the sources for the binaries
you are distributing.  Pointing to the Cygwin web site is not enough.  You
have to provide source code for every binary that you provide.
