Description Adhemerval Zanella 2024-06-20 13:34:35 UTC 
For instance, building socat 1.8 with a yocto clang based system shows:

      ./socat-1.8.0.0/xio-posixmq.c:119:8: error: 'mq_open' is unavailable: mq_open can be called either with 2 or 4 arguments
        119 |         mqd = mq_open(name, oflag, opt_mode, NULL);
            |               ^
      [...] /usr/include/bits/mqueue2.h:66:8: note: 'mq_open' has been explicitly marked unavailable here
         66 | __NTH (mq_open (const char *__name, int __oflag, mode_t mode,
            |        ^
      1 error generated.

Where GCC correctly does not show any warning message.
