With a new clone of latest git:
commit 89bdf4a2573720f664d2b80dbb6ea90b28aae058

Use correct value of BINARY_SIZE: GPU formats, and a couple Dhiru
missed (?)
and this change:
(unstable-jumbo)src $ git diff
diff --git a/src/common.h b/src/common.h

I still get that error when building linux-x86-64-clang (after doing an
unnecessary make clean).
I can reproduce the error with Fedora 18 (clang 3.1) and Fedora 16
(clang 2.9).
On my 32bit Fedora 16 system, building linux-x86-64-clang with the
common.h change mentioned above works.
