it looks like there are some error in configuration, because linker
tries to link interp.o and gcc3x-interp.o
which are the same interpreter code, except that gcc3x-interp is
modified a little through 'gnuification' step.
Normally, for building VM with GCC you should use only gcc3x one, and
if you dare to build VM with another compiler,
use interp.o instead.

a duplicate symbol means that same symbol (function or variable name)
are defined (do not mix with declared) in two or more object files at
global scope.
So, when linker tries to link them together into a single binary file,
it has a collision.

You can do this either by editing the CoreVM.xcodeproj/project.pbxproj file by hand (it has UUIDs for files so it can be tedious) or using Xcode itself (it has an arcane way of specifying include paths and #defines, so it can be tedious).
