I'm running into a problem with linking cc1gm2.  The -liconv seems to be 
a problem.

The funny thing is is that I have a libiconv.dylib in /usr/lib.
I think this might be Michael Lambert's issue.

-----------------------------------------------------------------------------------------------

In the build_dir/gcc Makefile there are several targets for cc1gm2 at 
various stages.
These have $(LIBS) as a dependency in addition to a part of the link line.
The -liconv as a dependency is what throws the build off.  The 
libiberty.a (the other part
is a plausible dependency for gcc.  But -liconv is strange.

I had hit this problem months ago and my solution was to trick the make 
with a bogus -liconv target:
-liconv:
  

I think Michael Lambert's solution is the correct one though.
