hrev45148 adds 3 changesets to branch 'master'
old head: bf4355a48e5a91c42f0bd7cdaa3d242d1d9f27c3
new head: 524bb6d3ec20b00a4d5c7035eb7ca97a09c9c94e
overview: http://cgit.haiku-os.org/haiku/log/?qt=range&q=524bb6d+%5Ebf4355a
----------------------------------------------------------------------------
7de6d45: Drop in unmodified fts/ftw implementations from FreeBSD HEAD (r245067).
4b5a13a: Add Haiku support.
This replaces the use of a few BSD-specific functions, as well
as the direct references to _open/_close et-al.
BFS doesn't support the FTS_NOSTAT directory link count optimization,
and no statfs() function is available, so we simply turn that off.
524bb6d: Restore FTS_WHITEOUT, guard it with __HAIKU__.
As per Jérôme Duval's code review in issue #9337.

Commit-Date: Thu Jan 10 23:26:48 2013 UTC
Add Haiku support.
This replaces the use of a few BSD-specific functions, as well
as the direct references to _open/_close et-al.
BFS doesn't support the FTS_NOSTAT directory link count optimization,
and no statfs() function is available, so we simply turn that off.
