Re: g++ 4 & MACOSX_DEPLOYMENT_TARGET=10.2

Am I correct in thinking that g++ 4-built targets won't run on 10.2?
10.2 doesn't have the dynamic version of the stdc++ library, just the
static version. But, even if you want to link with -static-libgcc, the
option is ignored in g++ 4 on 10.4.3 with the Xcode 2.2 update since
there is no static version. No warnings or anything.

Would using the 10.2 SDK make this work correctly (since a static
version _does_ live there)? Unfortunately, since I'm using a jam target,
I'm not so sure how to set it up. (Regular Xcode projects are a cinch
that way.)

No, gcc4.0 requires the dynamic libstdc++.dylib which is only deployed on 10.3.9 and later. To build for 10.2, use the SDK in conjunction with gcc 3.3. You can use the GCC_VERSION = 3.3 build setting to select this on a per-target basis (or GCC_VERSION_ppc for per-target, per-architecture).
