gcc编译成功，arm-linux-gcc编译报错，请高手指教！！
环境 RH9.0，gcc 3.2 arm-linux-gcc 2.95.3
编译以下程序gcc编译很顺利完成，但arm-linux-gcc 报错：
com1.c: In function `set_speed ':
com1.c:147: parse error before `int '
com1.c:149: `speed_arr ' undeclared (first use in this function)
com1.c:149: (Each undeclared identifier is reported only once
com1.c:149: for each function it appears in.)
com1.c:151: `name_arr ' undeclared (first use in this function)

[解决办法]
我试过了，可以编译通过。
你的arm gcc似乎有问题
