词法分析的小程序，对学编译原理的同学是个好例子

利用vc制作的模拟编译器的扫描程序，实现在输入字符串扫描分解为编译器能识别的符号。- Using the vc manufacture simulation compiler scanning procedure, realizes in the input character string scanning decomposes the mark which can distinguish for the compiler.

此工具是arm-linux-gcc交叉编译工具（cross-3.4.4），这个是我自己编译的，我试过，我用它编译了u-boot1.2.0没有问题，这个交叉编译器编了好长时间，我之前在网上搜了好长时间，但是没搜到，所以今天贡献出来，免得大家还得费时间去编译，我现在用是没有问题，如果有问题请多指教。希望热爱linux的同志们多贡献点好东西出来！-This tool is arm-linux-gcc cross compiler tools (cross-3.4.4), this is my own compiler, I tried, I use it to compile the u-boot1.2.0 no problem, the cross compiler made a good long time before I found online a long time, but never found, so this contribution to come out, so everyone will have time to compile, I now use is no problem, please advise if there are problems. Hope love linux comrades contribution to point out good things!
