That's what I've been doing.

The genobject.c error is new - I just fixed it, it was shallow.

The code is _nearly_ building fine. there's an issue in _sre.c with 
some code that either returns a Py_UNICODE* or an SRE_CHAR* (unsigned 
char*) in a void*. The code probably needs a refactoring to deal with 
that. There's also 
Python/compile.c: In function ‘int compiler_compare(compiler*, 
_expr*)’:
Python/compile.c:3065: error: invalid cast from type ‘void*’ to type 
‘cmpop_ty’
Python/compile.c:3075: error: invalid cast from type ‘void*’ to type 
‘cmpop_ty’
which I haven't looked at yet. Anyone else is welcome to fix these.
To get past those two, I've been building just those two files with 
gcc, with "make CC=gcc Python/compile.o Modules/_sre.o"
