I've confirmed that it still works on 10.5.  I was less successful  
than you on 10.4:

[dalejos-powerbook-g4-15:/Volumes/Data/tests] dalejo% /llvm-gcc4.2-2.2- 
ppc-darwin8.11.0/bin/llvm-g++  ctor1.C
/usr/bin/ld: unknown flag: -macosx_version_min
collect2: ld returned 1 exit status

This is a ppc32 machine running 10.4.11, but does not have a recent  
tools release installed on it.  What's the prerequisite here?

I think the problem with EH is that you're getting the unwinding  
library that was built as part of the llvm-gcc build.  That one will  
not work.  We want to pick up that library from a gcc build (or it may  
work just to remove the one that's there, if we require some other  
tools be installed).  It seems to use libgcc_s.10.[45].dylib on 10.5  
and libgcc_s.dylib on 10.4.  But it may be that 4.0 vs 4.2 is another  
variable, I'm not in a position to test all combinations.

I've used llvm-gcc to compile as far as a .o, then used g++ to link,  
and that works.  So I think this is the problem.
