• makes Framework bundle virtualenvs play nicer with
  OSX widgets
• based on work at https://github.com/gldnspud/virtualenv-pythonw-osx
• Needs code review (fragile, path based, uses tmpfiles)

TODO:

• What is the general fix for this for non-Framework installs?

I'll have to leave the real review and testing here to someone who has OS X. I'm a bit concerned about introducing a dependency on having a C compiler available; we've been trying to get rid of the dependency on Xcode for OS X, and this would further entrench it. Maybe it could be made optional with a flag to virtualenv?

The C file itself could be included as a base64 blob like other support files, but it's short enough I'm not sure that's really necessary.

Is than an alternate solution that doesn't require gccfor this? Could we provide a binary for this file (compiled) then use install_name_tool to rejigger it, just like I do in the fix for #168 ?

*This was migrated from pypa/virtualenv#211 to reparent it to the ``master`` branch. Please see original pull request for any previous discussion.*

This Pull Request was closed because it cannot be automatically reparented to the master branch and it appears to have bit rotted.

Please feel free to re-open it or re-submit it if it is still valid and you have rebased it onto master or merged master into it.
