I don't really know anything about ptexenc or libtool, so I can't give 
you a definitive answer.  But the README in texk/ptexenc says "`ptexenc' 
is a useful library...".  So I'm assuming that the purpose of the build 
in that directory is to produce the library.  And KPATHSEA_LIBS is 
apparently needed for that.  The only other thing I know is:

1. The Cygwin developer I'm working with suggested that patch.

2. It works, in the sense that the build completes and the shared 
ptexenc library is created.
