搞不明白，gcc3.0目录下的configure脚本代码感觉很奇怪，首部注释如下：
### WARNING: this file contains embedded tabs. Do not run untabify on this file.
# This file was originally written by K. Richard Pixley.
#
# Shell script to create proper links to machine-dependent files in
# preparation for compilation.
#
# If configure succeeds, it leaves its status in config.status.
# If configure fails after disturbing the status quo,
# config.status is removed.
#
子目录gcc下也有一个configure脚本，注释如下：
# Guess values for system-dependent variables and create Makefiles.
# Generated automatically using autoconf version 2.13
# Copyright (C) 1992, 93, 94, 95, 96 Free Software Foundation, Inc.
#
# This configure script is free software; the Free Software Foundation
# gives unlimited permission to copy, distribute and modify it.
问题一：这两个有什么区别和关系？
gcc4.0的configure脚本代码变动特别大，从运行时屏幕回显信息来看，gcc3.0目录下的脚本似乎是调用了子目录gcc下的脚本。
问题二：是这样么？
