rsync - May 2009 - Delta backup program planned (problem met for adding files)

Dear List,

Currently, I'm trying to implement a new feature to rsync. 

Delta back:
Well, it simply just backups diff blocks, and the program is able to
restore to any backup points.


Current problem met for adding files!

But I met a newbie problem here. I'm going to add six files, which are
diff.h/diff.c del.h/del.c and merge.h/merge.c.

I have modified Makefile.in.

When I add an function, compiler prints some error, see below:

And I have found that proto.h is generated automatically. So what I have
missed here in configuration (adding those six extra files)


I'm really appreciated any help form you. Thanks in advance.

OK, I have found the problem.

If I move the defination of "struct diff_file_list" to rsync.h, then
it's OK.

I think it might be something to do with OLDNEWS #line 642 since 3.0.0,
see below:

but I don't know why, can anyone help to explain? Thanks.
