minGW官方版与TDM版构建的差异(gcc -v)

通过查看gcc -v信息整理出下面的表格（虽然版本号不一致，但编译选项应该差不多的）

从这个表中两者编译选项还是有较大差异的，网上也有一份专门的资料( MinGW-GCC版本、wxWidgets库编译安装和生成程序的mingwm10.dll、 libgcc_s_dw2-1.dll依赖问题解决)，可以查看更多细节。

以前没有搞明白为什么从网上看到有的minGW编译时需要加上"-static-libgcc -static-libstdc++"两个选项，现在明白了，那是因为使用了官方minGW编译器的缘故，如果用TDM版就不需要了！

CodeBlocks自带的就是TDM-minGW。
