compile trunk with lua and gfxmenu

[edgar . soldin]

over the weekend I tried to figure out how to compile gfxmenu and lua 
together with grub from trunk. I didn't find an easy way. I tried to 
make an extra package similar to lua out of gfxmenu but stopped as I 
didn't knew how to integrate the missing header files.

My knowledge so far is how to check out, build grub trunk with 
grub-extras (incl. lua). How to checkout experimental including gfxmenu 
and build it. Trying to build experimental with grub-extras/lua results 
in an grub sprintf not found error.

Is there a way I missed, a documentation I overlooked?

Thank´s ede
