I used to take it out, but when it was moved after the -lm to find the right
pow(), I stopped.  What about fork vs vfork?  If I took the -lbsd off, I had
to fudge the config.h and undefine HAVE_VFORK.  That was the only function
from libbsd that was used.

So using libbsd broke 41 for you?  I'll have to double check my stuff again.
At one time I was compiling without libbsd after undefining HAVE_VFORK, so
maybe I got my correct results then and haven't rerun the regression tests
since the -lm and -lbsd were switched.

*sigh*...more crap to track down...now I know why AIX rhymes with "aches"...
