SUMMARY

See https://invent.kde.org/plasma/plasma-workspace/-/blob/034205dd9dc667f6abcf8fb8a53baa6094bb4449/ksmserver/legacy.cpp#L179 where ::select is called as:
>::select(fd + 1, &fds, nullptr, &fds, &tmwait);

This triggers a warning
```
 * /var/tmp/portage/kde-plasma/plasma-workspace-6.0.49.9999/work/plasma-workspace-6.0.49.9999/ksmserver/legacy.cpp:179:30: warning: passing argument 2 to ‘restrict’-qualified parameter aliases with argument 4 [-Wrestrict]
```

with gcc version 14.0.1 20240121 (experimental) (Gentoo Hardened 14.0.1_pre20240121 p16) at least, and it looks right.

From `select(3p`):
```
       int select(int nfds, fd_set *restrict readfds,
           fd_set *restrict writefds, fd_set *restrict errorfds,
           struct timeval *restrict timeout);
```

&fds is passed as both `readfds` and `errorfds` which is forbidden.
