+    /* 32 or 64 bit host? */
+    const char *bits = strstr (utsname.machine, "64") != NULL ? "64" : "32";

Will this work safely on all OS / arches ? I guess ia64, x86_64, sparc64
and ppc64  all give the right results.

One alternative would be using 'sizeof(void*) * 8', although if someone used 
a 32-bit set of libs on a  64-bit machine this would give wrong answer. 

Regards,
Dan.
