This means that the typedefs of int32 and uint32 within ogdi/include/ecs_util.h and vpflib/include/machine.h do not build. Attached is a patch that just defines them in terms of int and unsigned int (which is not a great solution). A better solution would be to include something like http://www.azillionmonkeys.com/qed/pstdint.h with OGDI, since Microsoft's compiler does not appear to ship with stdint.h or define int32_t/uint32_t.
Note that this problem also affects ogdi-3.2.0.beta2/vpflib/musedir.h where int32_t are used.
This has been fixed in CVS
