There might be some incompatibilities, for example due to how the HANDLE type is
declared. In C, you can use either 0 or NULL as a parameter to a function
accepting an integer or pointer. In D, you cannot. IIRC, some types were
declared differently in Druntime's modules and in the win32 bindings.

If breaking code were not an issue, the best solution would be to make HANDLE a
unique, opaque type (like a struct wrapping an intptr_t or void*) - which is
exactly how it should be treated. It would need to support assignment/creation
from "null" though.

This is why I don't approve of attempts to "fix" Windows APIs. It winds up being incompatible here and there, and breaks things.

We all know what HANDLE should be, but it isn't. The D definition of HANDLE should match what Microsoft's windows.h declares it as.

Any attempt to fix APIs to C libraries, etc., should be in a separate layer that goes on top of the D interface to those APIs.
