Wave one?
XCode uses the Apple version of the GNU Standard C++ Library v3, or
libstdc++-v3. AFIAK, the difference to the FSF version is limited to
add debugging support for container classes.
I'm not sure if Apple's specific changes are presently already part of
the FSF version, though - guess, they are.
The implementors claim that all of the Standard classes and functions
(such as string, vector<>, iostreams, and algorithms) will be fully
compliant.
You may find more info at <http://gcc.gnu.org/libstdc++/>, in
particular the FAQ.
I note that Rogue donated theirs to Apache and it's now in incubation.
That source code is available at <http://incubator.apache.org/stdcxx/>
As an aside why isn't the XCode libstdc++ source distributed with
developer tools?
Guess, because it's part of the complete GCC package and separate
snapshots for libstdc++ are not available.
libstdc++-v3 consists mainly of header files, so almost all "sources"
are already on your system as part of the installation.
If you would like to have all sources, you need to download the whole
GCC - which includes libstdc++-v3, either from the GNU web-site to get
the FSF version or from Apple to get the Apple specific version.
If I remember rigth, there is also an Apple branch for GCC on the GNU
web-site.
