I'm actually a 64-bit gcc 11.2.1 as bootstrap compiler, building with
gcc/g++/gdc -m32.

That's pretty close to my 10.7 system.  Btw., I just remembered that you
need a relatively new (for that system) version of Xcode on those ancient
systems.  I'm using the Xcode 4.6.2 command line tools on 10.7.  In a
10.8 VM I used Xcode 5.1.1 instead.  It may well be that you get weird
errors with earlier versions.  Iain Sandoe also has a patched version of
cctools at

        https://github.com/iains/darwin-xtools

However, I got along with the unmodified Xcode versions so far.=
