This check is needed because if static/dynamic linking is mixed incorrectly, it's possible for Clang and LLVM to end up with duplicate "copies" of libc++. This is not benign: Static variables are not shared, so equality comparisons that depend on pointers to static variables will fail. One such failure is std::generic_category(), which causes POSIX error codes to compare as unequal when passed between LLVM and Clang. I believe this is the cause of https://github.com/ziglang/zig/issues/11168 In order to avoid affecting build times when Zig is repeatedly invoked, we only enable this check for "zig env" and "zig version"
A general-purpose programming language and toolchain for maintaining robust, optimal, and reusable software.

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.
