Taken from BalaBit's internally used ivykis-0.20:

# AC_SEARCH_LIBS doesn't work properly on HP-UX 11.11, where pthread.h
# must be included, to link to the proper libs.
LIBS="$LIBS -lpthread"
AC_TRY_COMPILE([#include <pthread.h>],
               [pthread_mutex_t m = PTHREAD_MUTEX_INITIALIZER;],,
			                  AC_MSG_ERROR(pthreads support is required
							  to build ivykis modules.))

vimdiffing configure.ac's shows that 0.26 misses pretty much all older
UNIX specific checks. Probably we never submitted them.
