Using void pointers as universal arguments is widely used. However, when compiling a 64-bit target, the compiler doesn't like when an int is converted to a pointer and vice versa despite the presence of a cast. This is due to a width mismatch between ints (32 bits) and pointers (64 bits). The trick is to cast to a widening integer type such as intptr_t and then cast to void*. When appropriate, the INT_TO_POINTER macro is used instead of this double cast to make things clearer. The converse with POINTER_TO_INT is also done which also serves as good code annotations. While at it, remove unneeded casts to specific pointer types from void* in the vicinity, and move to typed variable upon function entry to make the code cleaner.
