cpplib: a few more cleanups

To: gcc-patches at gcc dot gnu dot org
Subject: cpplib: a few more cleanups
From: Zack Weinberg <zack at wolery dot cumb dot org>
Date: Sat, 5 Feb 2000 23:53:53 -0800
Cc: brolley at cygnus dot com
- Missed one #if 0 block in prev patch.
- Don't have two separate forward-declaration blocks in cpplib.c.
- Copyright updates.
- Minor formatting.

zw

	* cppalloc.c: Update copyright.
	* cpplib.c: Merge all the static function prototypes into one
	block.
	* cpplib.h: Remove #if 0 block.
