From 9909e232c06c030918ea370b6a4a9e55f0767749 Mon Sep 17 00:00:00 2001

Subject:         * interp.c (hash): Make this an inline function         when
 compiling with GCC.  Simplify.         * simpos.c: Explicitly include
 "sys/syscall.h".  Remove         some #if 0'd code.  Enable more emulated
 syscalls. Checking in more stuff.
