> In OpensslSecureRandom.c you use Linux-specific syscall gettid():
> static unsigned long pthreads_thread_id(void)
> {
> return (unsigned long)syscall(SYS_gettid);
> }
> Man page says:
> gettid()  is Linux-specific and should not be used in programs that are
> intended to be portable.
> This breaks hadoop-2.6.0 compilation on FreeBSD (may be on other OSes too).
