make emacs-unicode-2 in cygwin

[William Xue]

Hi,

I try to make emacs-u in cygwin
        ./configure
        make bootstrap

and it failed at
        'mv -f emacs.exe bootstrap-emacs.exe'

After reviewed the Makefile, I had some questions:

According to the code snippet from Makefile in src,
---8<--------------------------------------------->8---
bootstrap: bootstrap-emacs${EXEEXT}
bootstrap-emacs${EXEEXT}: temacs${EXEEXT}  
${lispsource}international/charprop.el
               $(RUN_TEMACS) --batch --load loadup bootstrap
               mv -f emacs${EXEEXT} bootstrap-emacs${EXEEXT}    
---8<--------------------------------------------->8---

it will rename the emacs.exe to bootstrap-emacs.exe, but when  
emacs${EXEEXT} will be made?

all: emacs${EXEEXT}
emacs${EXEEXT}: temacs${EXEEXT} ${etc}DOC ${lisp}
               LC_ALL=C $(RUN_TEMACS) -batch -l loadup dump
               -./emacs -q -batch -f list-load-path-shadows
