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
