I have inherited an open source C project that assumes that the

D has the size of long fixed at 64 bits, so a pointer now has
to be 64 bits.
If you want to exactly match the original C code's semantics, I
suggest translating (unsigned) long with c_long or c_ulong. You
can import them here:
```
import core.stdc.config: c_long, c_ulong;
```
Then you could add this:
```
static assert(c_long.sizeof == size_t.sizeof);
```
This will fail on Windows 64 bit, where C longs are 32-bit and
pointers 64-bit.
