The pthread_atfork() business is only required for broken pthreads
implementations that return a different value for getpid() from each
thread (i.e. Linux). He's got his ifdefs backwrds imho. The code in
rndunix.c:1270 should test for __LINUX__, instead of testing for all
other unixes :)
Try adding || defined(__FreeBSD__) to the set of tests on line 1270.
