This code is a bit odd (but a void* can certainly host a int on all architectures on which GDAL can be compiled), and certainly unused by anyone, so you could just remove the GetInternalHandle? Fundamentally, treating the bits of a pointer as if they were an integer is not a portable thing to do (although it can be made to work on many platforms). If the reason for the cast is to make the pointer opaque, then void* already achieves this, so the code could use void* instead of int.
