CCS6.1版本C2000编译器28377D器件无法支持attribute问题，移植EtherCAT从站代码，无法编译成功

andy sun

CCS版本：6.1

DSP：28377D

问题：移植EtherCAT从站代码，代码中带有巨多的__attribute__((aligned(1), packed))宏定义，在CCS6.1上也勾选了GCC选项（Build->advanced options->language options->enable support for gcc externsions）,重新编译后仍旧存在如下提示：

\EtherCAT\include\esc.h", line 167: error #1167: invalid attribute for "struct <unnamed>"

难道C2000不支持__attribute__编译么？？

可以把167行附近的代码都贴出来看一下吗？另外，编译器版本是多少？
