Bug 24408 – AF_INET6 duplicated in core.sys.linux.sys.socket

This program --- void main() { import core.sys.linux.sys.socket; import core.sys.posix.sys.socket; auto _ = AF_INET6; } --- fails to compile, giving the error --- q.d(60): Error: `AF_INET6` matches conflicting symbols: /usr/local/include/dmd/core/sys/linux/sys/socket.d(74): enum member `core.sys.linux.sys.socket.AF_INET6` /usr/local/include/dmd/core/sys/posix/sys/socket.d(1848): enum member `core.sys.posix.sys.socket.AF_INET6` --- core.sys.linux.sys.socket publicly imports core.sys.posix.sys.socket like it's supposed to, but it then declares AF_INET6 locally, which is unnecessary and causes the compilation error above, since it's declared in core.sys.posix.sys.socket, because it's standard POSIX.

@jmdavis created dlang/dmd pull request #16241 "Fix bugzilla issue 24408 - Remove duplicate AF_INET6 declaration." fixing this issue: - Fix bugzilla issue 24408 - Remove duplicate AF_INET6 declaration. It's already declared in core.sys.posix.sys.socket, so declaring it in core.sys.linux.sys.socket causes a conflict in code that imports both. The Linux-specific module publicly imports the POSIX one, so the declaration in the Linux one is unnecessary. This removes it. https://github.com/dlang/dmd/pull/16241
