C extensions should not be compiled under pypy

[Jonas Obrist]

When installing dulwich under pypy, the C extensions actually slow down dulwich rather than speeding it up. I had code going almost twice as fast by removing all the .so files in dulwich when running under pypy.

So ideally, when dulwich is installed under pypy, it should not compile C extensions.

Are you sure this is the case? As far as I understand the extensions are ignored by pypy anyway.

pypy doesn't if you had c extensions it will behave as close as possible to a propper python

did you just try to import something compiled against cpython into pypy?!?! its NOT ABI compatible

[Jelmer Vernooij (jelmer)]

No, but it looks like my pypy installation is actually broken - and thus I wasn't getting any extensions anyway.

Merged, thanks!
