Dear Maintainer,

Hello,

Using the rebuild infrastructure, your package fails to build with clang instead of gcc.

Error message is:
error: unknown warning option '-Wno-unused-but-set-variable'; did you
mean '-Wno-unused-const-variable'? [-Werror,-Wunknown-warning-option]

Full build log is available here:
http://clang.debian.net/logs/2015-03-25/grub2_2.02~beta2-22_unstable_clang.log

Thanks,
Joseph
