So, I just updated my 1.4.x tree and config'd my kernel. ../../../../kern/uipc_syscalls.c: In function `sockargs': ../../../../kern/uipc_syscalls.c:1037: `PAGE_SIZE' undeclared (first use in this function) PAGE_SIZE is defined in vm/vm_param.h should that be included in uipc_syscalls.c or in sys/param.h? Thanks --sjg
