Eclipse CDT Builtin Include Directories

There is a list of include paths.
有一个包含路径的列表。
Some are in bold and are project specific.
有些是粗体的，并且是特定于项目的。
Others are builtin:
其他是内置的：
For example:
例如：
/usr/include/C++/4.6/
/usr/include/x86_64-linux-gnu
etc
If I delete:
如果我删除：
work/.metadata/.plugins/org.eclipse.cdt.make.core/*.sc
The paths are automatically rescanned when Eclipse launches.
Eclipse 启动时会自动重新扫描路径。
I have gcc 4.6 and gcc 4.7 installed side-by-side.
我并排安装了 gcc 4.6 和 gcc 4.7。
When Eclipse rescans it only finds the 4.6 headers and not the 4.7 ones.
当 Eclipse 重新扫描时，它只找到 4.6 标头，而不是 4.7 标头。
My question is this: By what mechanism does Eclipse determine the list of builtin include paths? (and hence why is it only finding the 4.6 headers and not the 4.7 headers?)
我的问题是：Eclipse 通过什么机制确定内置包含路径的列表？（因此为什么它只找到 4.6 标头而不是 4.7 标头？）

This is controlled by the settings on Project->Properties->C/C++ Build->Discovery Options. By default, Eclipse will call g++ to discover the include directories. The first instance of g++ on the path will be the one that gets invoked. You can always set the full path to the compiler you want it to use for your project.
这由 Project->Properties->C/C++ Build->Discovery Options 上的设置控制。默认情况下，Eclipse 将调用 g++ 来发现包含目录。路径上的第一个 g++ 实例将被调用。您始终可以设置要用于项目的编译器的完整路径。
