[Distutils] Distutils improvements regarding header installation and building C extension modules

[Sylvain Corlay]

Hi all,

I am following up on this:

 - Is there any chance to get the has_flag and has_functions patches in?
 - Would there be any interest in a patch adding the
*pip.locations.distutils_scheme
*functionality to distutils?
 - Same question for the install_headers command item mentioned earlier.

Thanks,

Sylvain
