如何在mac上查看gcc版本号

linux能够很方便得查看gcc版本号，只需要输入gcc --version就能得到如下结果，能一目了然gcc版本是4.9.2

gcc (GCC) 4.9.2

但在mac上直接输入：gcc --version，却显示如下：

Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 7.3.0 (clang-703.0.31)
Target: x86_64-apple-darwin15.6.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

而其实在mac上比较方便快捷的方法其实是gcc -dumpversion，可以直接得到版本号，而且在linux下同样奏效

4.2.1
