 Neni to prace pro ./configure (tedy autoconf a ne automake:-).

## Check for libpthread
##
PTHREAD_LIBS_SAVE="$PTHREAD_LIBS"
PTHREAD_LIBS=error
AC_CHECK_LIB(pthread, pthread_attr_init, [
                      PTHREAD_CFLAGS="$PTHREAD_CFLAGS -D_REENTRANT"
                      PTHREAD_LIBS="$PTHREAD_LIBS_SAVE -lpthread" ])

dnl FIXME: test this on *BSD and report results immediatelly to the ml please
dnl If it is not found, try to check for c_r (on FreeBSD)
if test "x$PTHREAD_LIBS" = xerror; then
  AC_CHECK_LIB(c_r, pthread_attr_init, [
                    PTHREAD_CFLAGS="$PTHREAD_CFLAGS -D_THREAD_SAFE"
                    PTHREAD_LIBS="-pthread" ])
fi

dnl FIXME: do we really test here if libc contains this function?
if test "x$PTHREAD_LIBS" = xerror; then
        AC_CHECK_FUNC(pthread_attr_init, PTHREAD_LIBS="",
                AC_MSG_ERROR(not found library: pthread !!!))
fi

CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
LIBS="$LIBS $PTHREAD_LIBS"
