Path Problem When Emacs21 Built with Cygwin

[Yong LU]

This problem happens when building emacs 21.1.50 and leim with Cygwin.
After Emacs binary has been built, it goes into the leim directory
to compile lisp sources.  But since Cygwin maps all drive letters 
to things like "/cygdrive/x", where x is the drive, Emacs fail to 
load the libraries as the path in makefile is wrong.

I tried to fix this problem by changing "-l" parameters in leim/makefile,
but it doesn't work.  This time it says it can't find nt/CXTERM-DIC,

Administrator@ODYSSEY u:/lyongu/emacs21/emacs-21.1.50/nt

make: Leaving directory `/cygdrive/u/lyongu/emacs21/emacs-21.1.50/leim'

OTOH, I can build the leim tree if I cd into it before the make command.  
Is this a bug in the makefile or with gnu make/cygwin environment?
