据我所知，一些旧的gcc版本不支持@file选项。我不是很确定。有人能给予一些相关的提示吗？
供参考

@file
   Read command-line options from file.  The options read are inserted
   in place of the original @file option.  If file does not exist, or
   cannot be read, then the option will be treated literally, and not
   removed.

   Options in file are separated by whitespace.  A whitespace
   character may be included in an option by surrounding the entire
   option in either single or double quotes.  Any character (including
   a backslash) may be included by prefixing the character to be
   included with a backslash.  The file may itself contain additional
   @file options; any such options will be processed recursively.

谢谢
