This isn't true, here's the official list:

    * gcc-3.0.0: libstdc++.so.3.0.0
    * gcc-3.0.1: libstdc++.so.3.0.1
    * gcc-3.0.2: libstdc++.so.3.0.2
    * gcc-3.0.3: libstdc++.so.3.0.2 (Error should be libstdc++.so.3.0.3)
    * gcc-3.0.4: libstdc++.so.3.0.4
    * gcc-3.1.0: libstdc++.so.4.0.0
    * gcc-3.1.1: libstdc++.so.4.0.1
    * gcc-3.2.0: libstdc++.so.5.0.0
    * gcc-3.2.1: libstdc++.so.5.0.1
    * gcc-3.2.2: libstdc++.so.5.0.2
    * gcc-3.2.3: libstdc++.so.5.0.3 (Not strictly required)
    * gcc-3.3.0: libstdc++.so.5.0.4
    * gcc-3.3.1: libstdc++.so.5.0.5
    * gcc-3.3.2: libstdc++.so.5.0.5
    * gcc-3.3.3: libstdc++.so.5.0.5
    * gcc-3.4.0: libstdc++.so.6.0.0
    * gcc-3.4.1: libstdc++.so.6.0.1

Instead, he'll need gcc 3.3.x.  In general, it's of course wisest to
compile everything with the same toolchain.  At least approximately
the same version...

Nick, can you ask your library supplier to give you some version
numbers of the components of their toolchain?

I know how hard this can be, with proprietary software vendors...  And
sometimes you need to spend so much time helping them getting another
toolchain working for their build process, that you almost could have
rewritten their library yourself. ;)
