以“error: expected expression return nerr_raise(NERR_ASSERT,” 为keyword找到：

这贴里面这位Josh老兄给出的解法：
The following should fix this:
$ sudo mv /usr/bin/cc /usr/bin/cc.bak
$ sudo mv /usr/bin/c++ /usr/bin/c++.bak
$ sudo ln -s /usr/bin/llvm-gcc-4.2 /usr/bin/cc
$ sudo ln -s /usr/bin/llvm-g++-4.2 /usr/bin/c++
哦，原来是OSX下默认的compiler指向的问题， AOSP要使用gcc和g++，而原始的link指向是：
cc->clang
c++->clang++
（Clang： http://en.wikipedia.org/wiki/Clang）
所以我们需要将之前的link断开， 设置为gcc和g++。
$ sudo rm /usr/bin/cc /usr/bin/c++
$ sudo ln -s /usr/bin/llvm-gcc-4.2 /usr/bin/cc
$ sudo ln -s /usr/bin/llvm-g++-4.2 /usr/bin/c++
问题解决。
