How to use find-dired with MinGW?

[Matthias Meulien <m.meulien@free.fr>]

Hello,

After setting the following defaults (GNU Emacs 24.2.1 running on 
Windows XP Professional with a working MinGW installation):

(setq find-program "C:\\GNU\\MinGW\\msys\\1.0\\bin\\find.exe"
       grep-program "C:\\GNU\\MinGW\\msys\\1.0\\bin\\grep.exe")

I can `(find-dired "." "-name '*.gcda'")' but in the resulting buffer 
Dired fails to identify files due to a unexpected column (the first 
one); Here are the first 4 lines of that buffer:

   c:/Users/mmeulien.CELAD-F037/Documents/share/devel/:
   C:\GNU\MinGW\msys\1.0\bin\find.exe . "(" -name '*.gcda' ")" -ls

(...)

Do you know to get rid of that column?
