Where can I download the source code to the GNU C++ Standard Library?

Question

I downloaded the GNU Standard C Library (glibc) source code at http://ftp.gnu.org/gnu/glibc/ . Where can I find a similar download for their C++ Library?

I have googled around a bit and cannot seem to find it.

The only reason I need it is I want to see how it is implemented. So please don't give me links to binaries or to just the header files because it is the implementation source files that I am looking for.

Answer 1

它位于g ++（gcc-c ++）源文件中的libstdc++-v3目录中。

Answer 2
