Hunk #0:
    O_PATH does not exist on NetBSD.
https://github.com/google/mount-zip/pull/1

Hunk #1, #2:
    Work around an issue in librefuse <fuse_opt.h>. It has been
    incompatible with C++11 compilers. Fixed in HEAD:
    * http://mail-index.netbsd.org/source-changes/2021/12/01/msg134169.html
    * http://mail-index.netbsd.org/source-changes/2021/12/01/msg134170.html
    ([pho@] It's me who broke it.)

Hunk #3:
    fuse_setup() and fuse_teardown() are obsolete functions and has been
    (wrongly) removed from librefuse. Use fuse_main() instead, especially when
    nothing special needs to be done while mounting a filesystem and entering a
    main loop.
https://github.com/google/mount-zip/pull/1

    TODO: These two functions should be added back to librefuse, along with
    proper FUSE_USE_VERSION checks. Old applications are everywhere and it's
    clear we still need to support the decades old API given the amount of
    patches we ended up with for filesystems/fuse-*.
    ([pho@] I must admit it's me who removed them.)
