Thank you for reporting the problem.  I am not able to reproduce it with
current bleeding-jumbo, building it on Ubuntu 12.04 with their clang
(right after "apt-get install clang").  The build has worked just fine
for me.

I guess this is a bug in some version of clang.  In compiler.c, we're
using the "Labels as Values" GNU C extension when __GNUC__ is defined.
clang supports this extension too, and it defines __GNUC__ too.
However, it is not too surprising that the support for this extension
might be broken in some versions since relatively few programs use it.
