Sure. feel free to adapt on the basis of the attached patch.
Status is :
- completely functional 32 bits version with xpm, gif, jpeg, tiff. Able to
boostrap itself.
- the 64 bits version compiles and dumps, but fails to bootstrap (seems to
be looping inside elisp code).

Is there any interest in having a 64bits windows emacs ?

I have added two other files : a 64bits manifest for emacs.exe and a
w32compat.h header file that is needed to compile the above mentioned
libraries. In my case, this w32compat.h is included while compiling image.c
for example.

Feel free to comment and adapt for the release version.

Fabrice
