[PATCH] Fix a warning (on cygwin) to allow -Werror

Signed-off-by: Ramsay Jones <redacted>

Noticed while building 1.6.0 from the release tar-ball.

Also, I noticed that git_ntohl() is still defined in compat/mingw.h; is this
still required?  It's not a problem, just curious! (I don't have mingw
installed, so I can't test myself)

ATB,

Ramsay Jones
