I get the below mentioned errors on compiling the attached file with clang.
I have installed clang on a x86-64 machine (intel xeon core 2 duo
2.66ghz) running Suse linux for X86-64 with kernel 2.6.18.8-0.9
The same program is handled by clang without error messages on the
same machine running 32bit linux with the same kernel.
