Ah, yes. So it seems the ABI compatibility problem is not caused by 10.5/10.6 but by GCC 4.0/4.2.
libstdc++ on 10.5 seems to be compiled with GCC 4.0, but on 10.6 it's compiled with GCC 4.2.
In the meantime I could solve the problem even when using GCC 4.2. I had to implement some more what() methods (found them all by using the "nm" command as suggested), and now my app runs fine from 10.4 up to 10.6 on all PPC and Intel Variants (even 32 and 64 bit).

I am using GCC 4.0 for the 32-Bit PPC build, because GCC 4.2 is producing "ppc7400" code that runs on G4 and G5. But Mac OS X 10.4 also runs on G3 Macs and I wanted to support that. GCC 4.0 produces "ppc" code that runs on G3, G4 and G5.
I don't think that GCC 4.0 is generally needed for 10.4 deployment (if you don't need to support G3).
