C/C++跨平台的的预编译宏

我们在编译一些跨平台的程序的时候难免会遇到_WIN32 __linux__什么之类的SDK或者编译器环境预定义的宏。有很多，之前还分不清_WIN32 和WIN32的区别。不过这里还好有个列表，做个备忘。

Please send updates/corrections to predef-contribute.

If _AIX is defined, then the following macros can be used to determine the version. Notice that the macros indicates the mentioned version or higher. For example, if _AIX43 is defined, then _AIX41 will also be defined.
