The definition of HKEY__ as a struct with an unused int field is only the case in the Windows headers when `STRICT` is defined. From https://learn.microsoft.com/en-us/windows/win32/winprog/enabling-strict: > When STRICT is defined, data type definitions change as follows: > > - Specific handle types are defined to be mutually exclusive; for example, you will not be able to pass an HWND where an HDC type argument is required. Without STRICT, all handles are defined as HANDLE, so the compiler does not prevent you from using one type of handle where another type is expected. Zig's `opaque {}` already gives this benefit to us, so the usage of a struct with an unused field is unnecessary, and it was causing HKEY to have an alignment of 4, which is a problem because there are HKEY constants like HKEY_LOCAL_MACHINE (0x80000002) that are not 4-byte aligned. Without this change, the compiler would not allow something like HKEY_LOCAL_MACHINE to be defined since it enforces pointer alignment.

The ultimate goal of the Zig project is to serve users. As a first-order effect, this means users of the compiler, helping programmers to write better software. Even more important, however, are the end-users.
Zig is intended to be used to help end-users accomplish their goals. Zig should be used to empower end-users, never to exploit them financially, or to limit their freedom to interact with hardware or software in any way.
However, such problems are best solved with social norms, not with software licenses. Any attempt to complicate the software license of Zig would risk compromising the value Zig provides.
Therefore, Zig is available under the MIT (Expat) License, and comes with a humble request: use it to make software better serve the needs of end-users.
This project redistributes code from other projects, some of which have other licenses besides MIT. Such licenses are generally similar to the MIT license for practical purposes. See the subdirectories and files inside lib/ for more details.
