Dear SeaBIOS folks,
using Debian Sid/unstable and Clang 3.2 from Debian experimental
$ clang --version Debian clang version 3.2-1~exp6 (tags/RELEASE_32/final) (based on LLVM 3.2) Target: i386-pc-linux-gnu Thread model: posix
to build SeaBIOS, Clang throws the following errors.

I have no clue about assembler programming, so before reporting both errors to the Clang project, as it works with GCC, I want to make sure that Clang is mistaken here.
