Pass MSVC's C4826 warning.

MSVC has an optional warning which flags when 32-bit pointers get cast
into a 64-bit value. This is a little overaggressive I think, but to
ease compiling in projects with aggressive warnings, fix this by just
casting to const void * directly. Modern GCCs seem to compile it just
fine.
