This is a known misfeature of the versions of Windows that are NT
descendants: when they see a DOS program that chdirs into a different
directory, they switch the DOS box's current directory to its 8+3
alias.  Since the prompt uses that value of the current directory, you
see the ugliness when you are back at the prompt.

I don't know of any solution to this (except not to run DJGPP
programs).  I usually do a "cd ..\curdir" to regain the LFN name
again.
