STLport uses __stl_{new,delete} which uses ::operator {new,delete}
from g++'s <new> header. I don't see any mixing in preprocessed sources.
Moreover libstdc++ isn't linked in the testcase.

$ ldd testDrv
        linux-gate.so.1 =>  (0xffffe000)
        libstlport.so.5.0 => /local/devel/buildenv41/i486-gnu-linux/
                             STLport/lib/libstlport.so.5.0 (0x5556d000)
        libc.so.6 => /lib/tls/libc.so.6 (0x55612000)
        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x5572c000)
        libpthread.so.0 => /lib/tls/libpthread.so.0 (0x55734000)
        libm.so.6 => /lib/tls/libm.so.6 (0x55746000)
        /lib/ld-linux.so.2 (0x55555000)

[1]
It has faster std::string implementation
which I need for large Tcl/Tk based GUI.

[2]
I'm using it in multiplatform project with different compilers
(win32(vc2003), linux(g++), solaris(g++, sunworkshop)).
It gives me a one STL implementation for whole project.
