in misc/bits/syslog.h some functions return a value when the return value is 
void.

__extern_always_inline void
syslog (int __pri, __const char *__fmt, ...)
{
  return __syslog_chk (__pri, __USE_FORTIFY_LEVEL - 1, __fmt, __va_arg_pack ());
}

__extern_always_inline void
vsyslog (int __pri, __const char *__fmt, __gnuc_va_list __ap)
{
  return __vsyslog_chk (__pri,  __USE_FORTIFY_LEVEL - 1, __fmt, __ap);
}
