gcc 出现问题：There is NO warranty; not even for MERCHAN ...

今天查看gcc的版本，出现如下问题：

C/C++ code

    ~$ gcc --version
    gcc (Ubuntu/Linaro 4.4.4-14ubuntu5) 4.4.5
    Copyright (C) 2010 Free Software Foundation, Inc.
    This is free software; see the source for copying conditions.  There is NO
    warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

查看arm-linux-gcc也有这样的问题，
C/C++ code

    ~$ arm-linux-gcc --version
    arm-none-linux-gnueabi-gcc (Sourcery G++ Lite 2009q1-203) 4.3.3
    Copyright (C) 2008 Free Software Foundation, Inc.

这是什么意思，这对编译有影响吗？请指教，谢谢！

这是免责声明吧
都是这样的，不影响使用
