GHC 6.8.1 on powerpc OS X 10.5

So I decided to try and route around the ld/collect2 problems with ghc-6.8.1 not
working on powerpc OS X 10.5

OS X 10.5 (Leopard) uses XCode 3.0 which has a gcc-4.0 toolchain.

So I try to get another gcc & binutils from macports.  This failed.  All of
gcc40 gcc41 gcc42 and gcc43 failed to compile successfully with macports.

So I switched to trying fink, which offers gcc-4.2.2 and this did compile and
install.  Hooray.

Unfortunately, using ghc-6.6.1 (from when I ran OS 10.4 Tiger) with gcc-4.2.2
does not work when compiling ghc-6.8.1 (at least on this platform).

Running "../utils/genprimopcode/genprimopcode --primop-tag" produces "Illegal

There were other odd messages during the make,such as in this early output:

The '-no-cpp-precomp' and 'section difference ...' and 'use a symbol ...'
messages repeat often.

I looked at trac, and can only find the closed ticket
relating to gcc-4.2 issues.

Does anyone have suggestions? hints? bad jokes?
