所有的gcc版本都支持gcc的@file選項嗎？

據我記得一些舊的gcc版本不支持@file選項。我不太確定。有人能給出與此相關的任何指針嗎？所有的gcc版本都支持gcc的@file選項嗎？

僅供參考

@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.

感謝

的[在線文檔]（http://gcc.gnu.org/onlinedocs/）可以一路返回到版本sion 2.95.3。這可能需要一些時間，但很容易檢查所有版本。 – 2013-02-27 08:06:22

另外，假設該選項在某個版本之前的所有版本中都存在，則可以使用二分搜索。 – Electro 2013-02-27 08:09:20

看來gcc 4.1.2不支持它。 – 2013-02-27 09:10:02

這是致力於GCC源位置：

2005-11-23 Mark Mitchell <[email protected]> 

    * 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.

根據釋放history，這應該使它成爲GCC 4.1
