On 10.20, there is no pthread(3), but the note in string(3) is the same
It is however necessary to define -D_REENTRANT additionally to using
-Ae or D_HPUX_SOURCE. I have checked string.h and sys/stdsyms.h:
on 10.20 -D_REENTRANT is not automatically set!!
Kevin's change to configure solves the problem.
