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.
$ git show
commit f465e1ec1b01826100c92b890487a2ab09bfe2c1
Author: Kevin O'Connor <ke...@koconnor.net>

Minor - introduce numeric defines for the IVT offset of hw irqs.
$ make menuconfig # coreboot chosen, see attached
$ CC=clang make

make: *** [out/ata.o] Fehler 1
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.
Thanks,
Paul
