据我记得一些较旧的 gcc 版本不支持 @file 选项。我不太确定。有人可以提供与此相关的任何指示吗？

以供参考

   @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

这是在此处提交给 gcc 源的：

2005-11-23  Mark Mitchell  <mark@codesourcery.com>

    * doc/invoke.texi: For man pages, include gcc-vers.texi.
    List @file in the option summary.  Include the libiberty
    documentation for @file.
    * gcc.c (main): Call expandargv.
    * Makefile.in (gcc-vers.texi): Define srcdir.

根据发布历史，这应该已经进入 GCC 4.1
