I am sorry for causing this build error. The reason I used
const was that the address parameter was not supposed to
to be modified by the callee. Looking at /usr/include/dlfcn.h
on my Linux box it also seemed palatable to the dladdr()
function so I went ahead with it.

By the way, we've had discussions on the utility of using
const qualifiers in C on the GCC list recently:

Thanks,
Ranjit.
