I only know about vanilla Mac OS X with Apple's developer tools, but I  
just ran some checks on several systems that have developer tools  
installed.

On Leopard (Darwin 9.6.0) Apple supports both gcc 4.0 and 4.2.  Both  
compilers use the same stdc++ libraries with the same headers.  The  
headers seem to be in /usr/include/c++/4.0.0:

        $ find /usr/include -name iostream
        /usr/include/c++/4.0.0/iostream
        /usr/include/gcc/darwin/3.3/c++/iostream

The location of these headers seems to remain the same across the SDKs  
for Panther, Tiger, Leopard and all versions of the iPhone OS, so I  
would expect that path to be accurate for any version of Darwin up to  
9.6.0 that supports gcc 4.x.

In Snow Leopard (Darwin 10.0.0) the situation seems somewhat  
different, as there are separate headers for gcc 4.0 and 4.2:

        $ find /usr/include -name iostream
        /usr/include/c++/4.0.0/iostream
        /usr/include/c++/4.2.1/iostream

I hope this helps.  Please let me know if I can provide additional  
information.

Best wishes,
