From a2d91340f322fed39bdaf02391b8be01dffb7869 Mon Sep 17 00:00:00 2001
From: Andrew Cagney <cagney@redhat.com>
Date: Sun, 9 Apr 2000 12:17:43 +0000
Subject: Remove ``-W -Wall'' from top-level Makefile/configure. Add ``-W
 -Wall'' to sub-directories bfd, binutils, gas gprof, ld and opcodes by the
 addition of WARN_CFLAGS to Makefile.am and configury to set it.  Add
 configure option --enable-build-warnings. Re-generate all and sundry using
 auto*-000227.
