From e572c0c68c9d1a48595039af480e18e7d4bdb292 Mon Sep 17 00:00:00 2001
From: "Kaveh R. Ghazi" <ghazi@caip.rutgers.edu>
Date: Wed, 6 May 1998 07:58:27 +0000
Subject: Be more careful when including <time.h> and <sys/file.h> in system.h.

Consolidate O_RDONLY/O_WRONLY fallback definitions from various files
into system.h.
        * system.h: Wrap time.h and sys/file.h in autoconf checks.
        Provide default definitions for O_RDONLY and O_WRONLY here.
        * cccp.c, cpplib.c, fix-header.c, gcc.c, protoize.c: Not here.
