在对OSspecific静态链接库进行编译时出现下列问题：
程序中的string.H与系统头文件string.H的冲突：
程序中的string.H位于../../src/OpenFOAM/lnInclude中，而系统的string.H位于 MingW\include中，在CodeBlocks工程文件中只定义了两个搜索路径即../../src/OpenFOAM/lnInclude和../../src/OSspecific/lnInclude，这样的话在进行编译时的编译过程出错：

这里的问题在于cstring中也包含了<string.H>(Line51)，这里的string.H应该是系统头文件（位于MingW\include中），本应在系统头文件目录中找，但是却在../../src/OpenFOAM/lnInclude和../../src/OSspecific/lnInclude中找，结果找到的是位于../../src/OpenFOAM/lnInclude中的string.H，因而造成了上述编译错误.
如何改正这一问题呢，经过反复摸索终于被我搞定，就是修改cstring文件第Line51行:
原代码：#include <string.H>
修改后：#include_next <string.H>
经试验，经过上述修改后，程序便正常编译了，呵呵！
看来系统头文件也不是完全正确的，还是有bug的。
