If you can build git with gcc, you should be able to run 'make sparse'
(modulo bugs, of course!). Having said that, I build sparse from source
and (on Linux) I'm running:

  $ sparse --version
  v0.5.0-30-gca3309e
  $

The most up-to-date (from git://git.kernel.org/pub/scm/devel/sparse/sparse.git)
is actually:

  $ sparse --version
  v0.5.0-41-g6c2d743
  $ 

which should work just fine. (I also run sparse on cygwin and MinGW).

No, I am simply building the 'pu' branch (currently @ 028c360).

Hmm, I didn't give it any thought, but don't you want that to be '== NULL'?
(you don't want to use a NULL lock->lk->fp in the following fprintf()).
Or simply '!fdopen_lock_file(lock->lk, "w")' I suppose.
