And here are patches on top to squash the remaining "may be used uninitialized" warnings (from gcc-4.6 -O2) that they were meant to address.

The change descriptions are placeholders. In an ideal world, someone interested might pick these up and rebase against master to skip the relevant parts of the above patch altogether.

Jonathan Nieder (6):
  match-trees: kill off remaining -Wuninitialized warning
  run-command: initialize failed_errno to 0
  diff --submodule: suppress -Wuninitialized warning by initializing to
    NULL
  rsync transport: clarify insert_packed_refs
  wt-status: protect against invalid change_type
  fast-import: suppress -Wuninitialized warning by initializing to NULL
