我在niosII5的IDE环境下，用系统给的hello_world hello_led 等C++程序，且是standard的系统配置，怎么编译就是通不过呢？出错信息如下：

make -s all Compiling alt_busy_sleep.c... /cygdrive/d/altera/kits/nios2/components/altera_nios2/HAL/src/alt_busy_sleep.c: In function `alt_busy_sleep': /cygdrive/d/altera/kits/nios2/components/altera_nios2/HAL/src/alt_busy_sleep.c:69: error: parse error before '/' token /cygdrive/d/altera/kits/nios2/components/altera_nios2/HAL/src/alt_busy_sleep.c:89: error: parse error before '/' token /cygdrive/d/altera/kits/nios2/components/altera_nios2/HAL/src/alt_busy_sleep.c:106: error: parse error before '/' token /cygdrive/d/altera/kits/nios2/components/altera_nios2/HAL/src/alt_busy_sleep.c:106: error: parse error before ')' token /cygdrive/d/altera/kits/nios2/components/altera_nios2/HAL/src/alt_busy_sleep.c:123: error: parse error before '/' token /cygdrive/d/altera/kits/nios2/components/altera_nios2/HAL/src/alt_busy_sleep.c:123: error: parse error before ')' token make[1]: *** [obj/alt_busy_sleep.o] Error 1 make: *** [system_project] Error 2 Build completed

请高手指教！！
