Didn't we discuss this already and concluded that it wasn't a problem?
I know I've committed files from nt/ that I had checked out with -kb.

I asked a question about that, but didn't see any replies.  All my
references, including the CVS manual, indicate that -kb will be used
henceforth with any CVS operation.  If you (or someone else) know
otherwise, please tell the details.

I never said that committing files will be impossible; binary files
can be committed as well.  The question is, what does CVS think about
these files, and whether all versions have diffs associated etc.

Sorry, I missed that somehow.

Anyway, I'm still confused.  Assuming that I checkout a file with -kb,
and that file is not recorded as binary in the repository, would
commands such as "cvs diff", "cvs annotate", etc. work exactly as when
no -kb was ever used on that file?  If that is so, then the CVS people
surely need to redo their manual's description of "co -kb" and of the
binary files issue!

Also, given this description, as written by Andreas:

was this always true, or is this some change in the recent versions of
CVS, and if latter, which version started behaving like that?

And what will "cvs ci" do for a file whose entry in CVS/Entries says
it has the -kb option set?  How will this be different from a file
without the -kb option?

Finally, if "co -kb" indeed has only a local effect, and none of the
other commands, like ci, diff, up -j, etc. are affected, it sounds
like Windows users should be told to checkout the whole tree with -kb,
right?

TIA

They seem to, yes.

It might be worth trying. AFAIK all the other problems with line ends
have been fixed so it should work.

cvs diff, annotate, etc. do work as if the files weren't checked out with -kb.

I think the -kb entry in CVS/Entries does not affect "cvs ci" unless
the file is marked as "-kb" on the repository. None of the commits of
nt/nmake.defs, nt/makefile.w32-in, etc. that I've done seem to have
had any adverse effect.

Not sure if they should be told to, but at least there is no problem
if they do: I just checked out a -kb tree and built it with MSVC with
no problem whatsoever.

Thanks for the footwork.  I've now removed the warning from
nt/INSTALL.

I did that as well (but with MinGW).  I will run with this setup for a
while and see if I encounter any problems.

Found one already: "cvs up" never uses patches with this setup, it
always sends the entire new version of the files downstream.  That is,
if the Emacs tree is checked out with -kb, you will never again see
messages like this:

  P lisp/ChangeLog

but always

  U lisp/ChangeLog

This might be a problem with slow connections, but otherwise it's
harmless, I guess.

A more serious problem is that automatic merges are probably not
supported either (although I didn't try).

That was covered in the message you missed.
