__fatal_error routine doesn't check strerror_r() return value, which results in the following compile time warning: posix_timers.c: In function ‘__fatal_error’: posix_timers.c:31:9: warning: ignoring return value of ‘strerror_r’ declared with attribute ‘warn_unused_result’ [-Wunused-result] 31 | strerror_r(errno, buf, sizeof(buf)); Fix this by adding a check for return value and error handling appropriate for the GNU-specific strerror_r() in use in __fatal_error(). Check if return string is null and handle accordingly. From Linux strerror_r() manual page: "The GNU-specific strerror_r() returns a pointer to a string containing the error message. This may be either a pointer to a string that the function stores in buf, or a pointer to some (immutable) static string (in which case buf is unused). If the function stores a string in buf, then at most buflen bytes are stored (the string may be truncated if buflen is too small and errnum is unknown). The string always includes a terminating null byte."
