[PATCH v2 0/4] port upload-archive to Windows

Here's the updated version of this series. Changes since last time:
 - Patch 3/4 is new, makes enter_repo take const-input
 - Patch 4/4 (formerly 3/3): added a call to enter_repo to make sure
   the path-argument is taken into account.

Erik Faye-Lund (4):
  compat/win32/sys/poll.c: upgrade from upstream
  mingw: fix compilation of poll-emulation
  enter_repo: do not modify input
  upload-archive: use start_command instead of fork
