Hello.

I would like to have a feature on platform module (or sys or somewhere) that can tell distutils or distutils2 that this platform (be it PyPy or Jython) is not able to compile any C module. The purpose of this is to make distutils bail out in more reasonable manner than a compilation error in case this module is not going to work on anything but CPython. What do you think? +1 I think we could have a global variable in sys, called "dontcompile", distutils would look at before it tris to compile stuff, exactly like how it does for pyc file (sys.dontwritebytecode)

Or... wait : we already know if we are using CPython, or Jython reading sys.platform.

So I could simply not trigger the compilation in case sys.platform is one of the CPythons and keep in distutils side a list of the platform names, Extension is incompatible with.

That makes me wonder : why don't we have a sys.implementation variable ? (cython/jython/pypi), since we can have several values for cython in sys.platform
