From e5a1a2ea99b37e6141050b334a54d0c3f30a139e Mon Sep 17 00:00:00 2001
From: Ian Lance Taylor <ian@airs.com>
Date: Wed, 26 Jun 1996 20:28:29 +0000
Subject: [PATCH] * All files: Define FILHSZ, AOUTSZ, AOUTHDRSZ, SCNHSZ,
SYMESZ, AUXESZ, LINESZ, RELSZ as numeric constants rather than uses of
sizeof. Define AOUTHDRSZ in all files. * pe.h (AOUTSZ):
Define by adding to AOUTHDRSZ.
