Mon May 19 18:59:33 1997 Mike Meissner <meissner@cygnus.com>
* configure.in: Check for getpid, kill functions.
* config{.in,ure}: Regenerate.
* insns (do_trap): Add support for kill, getpid system calls.
* sim-main.h (errno.h): Include.
(getpid,kill): Define as NOPs if the host doesn't have them.
Mon May 19 14:58:47 1997 Andrew Cagney <cagney@b1.cygnus.com>
* sim-calls.c (sim_open): Set the simulator base magic number.
