dwt.c:222: warning: integer constant is too large for 'long' type

jp3d.c:1526: warning: integer constant is too large for 'long' type

At least for the dwt.c the issue is that a pointer is cast into an integer type. Originally the pointer was being cast into an int which would cause a warning and potentially bugs on architectures in which a pointer and an int are not the same size. The currently committed fix is to cast the pointer into a long instead of and int. While this fixes the problem on the architecture I'm interested in (MacOSX/Darwin) where long is 4bytes when building in 32bit and 8bytes when building in 64bit, a better approach might be to use an integer type that is promised to track the pointer size such as size_t or intptr_t.

Thanks Joël. I replaced the 'long' of r724 in dwt.c with 'size_t'.

However, it seems this issue (61) is related to another kind of problem specific to libjp3dvm.
