Problems with CVS

[Akim Demaille]

I have some problems with CVS that I don't understand, maybe someone
will have an idea.

For a start, when I update, including with cvs up -C, I face these
warnings:

| cvs update: move away `data/.cvsignore'; it is in the way
| C data/.cvsignore
| cvs update: move away `data/Makefile.am'; it is in the way
| C data/Makefile.am
| cvs update: move away `data/README'; it is in the way
| C data/README
| cvs update: move away `data/c++.m4'; it is in the way
| C data/c++.m4
| cvs update: move away `data/c.m4'; it is in the way
| C data/c.m4
| cvs update: move away `data/glr.c'; it is in the way
| C data/glr.c
| cvs update: move away `data/glr.cc'; it is in the way
| C data/glr.cc
| cvs update: move away `data/lalr1.cc'; it is in the way
| C data/lalr1.cc
| cvs update: move away `data/location.cc'; it is in the way
| C data/location.cc
| cvs update: move away `data/yacc.c'; it is in the way

Even if I remove them and ask for cvs up -C, next time I have the same
problem.  I thought it was harmless, but as a result my previous patch
was not checked in completely, the data/ part was not included.  When
I went in data/ to check in my changes, it worked, but it also checked
in inexisting changes to files I have not touched (for instance
http://cvs.savannah.gnu.org/viewcvs/bison/data/Makefile.am?root=bison&r1=1.12&r2=1.13).

Does somebody know what's wrong with my setup?
