Subject: [PATCH] whitespace and include guards

2002/04/14 13:56:45-00:00 !antona
cleanup header files.

2001/12/15 05:13:08-00:00 !antona
Remove atomic ops and add compiler version check.

2001/04/08 03:02:55-00:00 !antona
Added cvs Id header.

Everything compiles again! Yey! (Don't know about working though, haven't tried
it... So be careful...)
The definitely final find_{first_}attr() functions are in place. Currently
still no support for attribute lists.
The two new _RE files contain the C-fied and more or less (more less than more
actually) cleaned up functions from the ntfs driver. Once they are cleaned
up (find_attr() is already completed but I left it in the _RE files for future
reference/educational value) and modified to suit my ideas of how they should
work, which are not quite the same as the driver way, they will make it into
attrib.[ch].
If anyone gives the new code a try, I would be interested in whether it worked
or not... (-;

Forgot to add the new support.h

(Logical change 1.5)
