* hurd/new-fd.c (_hurd_new_fd): Initialize fcntl flags. * hurd/port2fd.c (_hurd_port2fd): Reset the fcntl flags when installing PORT in the descriptor cell. 1999-08-19 Roland McGrath <roland@baalperazim.frob.com> * sysdeps/mach/hurd/i386/intr-msg.h (INTR_MSG_TRAP): Mark OPTION and TIMEOUT as outputs of the asm to indicate that the signal thread might mutate them. * hurd/intr-msg.c (_hurd_intr_rpc_mach_msg): Short circuit to plain mach_msg if only sending or only receiving (i.e., not an RPC). When making an RPC that might get interrupted, save OPTION and the portion of the message buffer that gets clobbered by an EINTR reply message, and properly restore them before attempting to retry the request message send.
