I think the cygwin path name problem can be solved by the use of relative 
path names.  I've changed the two occurrences of $CURDIR in leim/makefile 
to "." and it works.  I'm not sure if there're any other systems that 
would rely on the use of $CURDIR.

OTOH, the problem of not finding the correct pwd seems to be a very 
subtle bug.  I cannot reproduce it everytime.  But when I do, emacs
gets a wrong pwd (I've changed batch-titdic-convert to print out
the result of (pwd)):

This could be temporarily avoided by appending all directory names with
"../leim/", until the real bug is found out.
