Hi,

The diff below fixes one warning during configure and two during compilation on OpenBSD (and maybe elsewhere):

checking pthread_np.h usability... no
checking pthread_np.h presence... yes
configure: WARNING: pthread_np.h: present but cannot be compiled
configure: WARNING: pthread_np.h:     check for missing prerequisite headers?
configure: WARNING: pthread_np.h: see the Autoconf documentation
configure: WARNING: pthread_np.h:     section "Present But Cannot Be Compiled"
configure: WARNING: pthread_np.h: proceeding with the compiler's result
configure: WARNING:     ## -------------------------------------------- ##
configure: WARNING:     ## Report this to varnish-dev@varnish-cache.org ##
configure: WARNING:     ## -------------------------------------------- ##

varnishadm.c:190: warning: implicit declaration of function 'add_history'

cache/cache_main.c:82: warning: implicit declaration of function 'pthread_set_name_np'

Comments? OK?
