以前我曾为了让VC++等编译器支持C99的整数类型，编写了同名的stdint.h、inttypes.h来智能处理（http://www.cnblogs.com/zyl910/archive/2012/08/08/c99int.html）。现在将其升级到v1.01版。
一、改动说明
1.1 包含目录问题
在1.00版，我编写的头文件与系统头文件同名，利用“#include "XXX"”与“#include <XXX>”的区别，使其智能使用系统头文件。
这样做的优点是基本不需改动代码（只需将“#include <stdint.h>”改为“#include "stdint.h"”），而且易读性好，一看就知道是C99整数类型。
后来使用时发现该方案存在包含目录问题——我的stdint.h、inttypes.h不能放在项目include目录中。
这是因为“#include <XXX>”时会优先检查项目include目录，而后才是系统include目录。
如果将我的stdint.h、inttypes.h放在项目include目录中，会导致循环引用，无法定位到系统头文件。
所以，只能将我的stdint.h、inttypes.h放在项目src目录。
当项目较大时，会建立多级子目录来存放源码。这时只有将stdint.h、inttypes.h复制到各个子目录中，管理起来不方便。
于是我决定将我的stdint.h、inttypes.h分辨改名为auto_stdint.h、auto_inttypes.h，这样就可以放在项目include目录中了。缺点是使用时麻烦一点，要包含auto_stdint.h、auto_inttypes.h。
既然文件改名了，宏也要改名——
__AUTO_STDINT_H_INCLUDED（原_STDINT_H_ALL_）。
__AUTO_STDINT_H_USESYS（原_STDINT_H_SYS_）。
__AUTO_INTTYPES_H_INCLUDED（原_INTTYPES_H_ALL_）。
__AUTO_INTTYPES_H_USESYS（原_INTTYPES_H_SYS_）。
1.2 编译器兼容性
测试了 Visual C++ 2008。发现它果然不支持stdint.h与inttypes.h。
测试了 Visual C++ 2012。发现它支持stdint.h，仍不支持inttypes.h。
