Comment (by warner):

 As an experiment, I modified `install_egg_info.py` to change:

 {{{
  unpack_archive(self.source, self.target, skimmer)
 }}}

 with:

 {{{
  unpack_archive(self.source, "\\\\?\\" + os.path.abspath(self.target),
 skimmer)
 }}}

 and I was able to `pip install .` spake2 (with the artificial dependency
 on pycryptopp) in $AAAA directories up to 180 chars long. At
 len($AAAA)=185, a different error occurred (`pip.download.unpack_file_url`
 calling `shutil.copytree`, copying the egg-info directory into a tempdir).
