The buildbots[1] don't seem to agree, and it builds fine for me on
Windows.  In order of destructiveness, try these:

      Without -j2, see if there's a race somewhere.
   make distclean
      Clear out nearly all generated files.
   hg purge --all
      Clear out everything that's not checked in (this
      includes untracked and ignored files). You may
      need to enable the purge extension,
      `hg --config extensions.purge= purge --all`
      And I would suggest checking the output of
      `hg purge --all -p` before you do it to make sure
      you're not obliterating anything you want to keep.
   hg up null && hg purge --all && hg up default
      Rebuild the repository from scratch (without a full clone).
