[Pythonmac-SIG] Error trying to build a extension on python 2.5 (stdarg.h problem)

[Leonardo Santagada]

I read the archives of the list, but I have XCode and the universal  
SDK. I'm having a problem trying to build an extension, here is the  
output:

and the setup.py file is here:


from distutils.core import setup
from distutils.extension import Extension
from distutils.ccompiler import get_default_compiler

PYPY_INCLUDE_DIR = '/Users/retype/pypy-dist/pypy/translator/c'

extra_compile_args = []
if get_default_compiler() == "unix":
     extra_compile_args.extend(["-Wno-unused-label",
                                "-Wno-unused-variable"])

setup(name="testing_1",
       ext_modules = [Extension(name = "testing_1",
                             sources = ["testing_1.c"],
                  extra_compile_args = extra_compile_args,
                        include_dirs = [PYPY_INCLUDE_DIR])])


so although this came from pypy, I really think the problem is either  
on my machine or on distutils (probably my machine, as I don't  
believe this could break with such a simple script).
do anyone know how can I fix this?
