[omniNotify] 64 bit notifd on Solaris 2.8 core dumps immediately

[Mark Zimmerman]

sizeof(void*) = sizeof(long) always. This code by itself is OK but the
problem is created higher up in the call tree. It is not the size of
the pointers that is the problem but rather the size and alignment of
the data element being pointed to. It starts out as a reference to a
32 bit value but is transmogrified through perverse magic into what it
thinks is a pointer to a 64 bit value.
