BURG doesn't compile with --with-platform efi

[Ophir LOJKINE]

Hi!
I'm on Ubuntu stable (10.04), and BURG doesn't compile for me.
Steps to reproduce:
bzr branch lp:burg
./autogen.sh
./configure --with-platform=efi
make

What I get:
CC Blahblah
then:
cc1: warnings being treated as errors
loader/i386/efi/linux.c: In function ‘grub_linux_setup_video’:
loader/i386/efi/linux.c:582: error: passing argument 1 of ‘gop->blt’ from incompatible pointer type
