I understand. FWIW binary/feature/x86-woe/cvs-1-12-13a.zip has been
uploaded to the area on http://download.savannah.gnu.org/releases/cvs/

which has a separate important windows client fix.

Ahhh... now, on gentoo-linux I KNOW you can fetch a copy of the
cvs-1.12.13 sources and apply the patch of my last e-mail to see if it
helps you or not.

You may wish to try using the CVS_CLIENT_LOG environment variable as Jim
suggested. However, it might expose parts of your file, so please do
look at the ${CVS_CLIENT_LOG}.in and ${CVS_CLIENT_LOG}.out files closely
before you just send them along to us.

I am also interested to know the offset in bytes of the conflict markers
into the file.

I am expecting that the ${CVS_CLIENT_LOG}.in file will contain lines
like this:

Entry /file/1.5/+=//
Unchanged file1
update

And that the ${CVS_CLIENT_LOG}.out file will contain lines like this:

first-dir/
MT text C 
MT fname file
MT newline
error  

if everything is working correctly. The "+=" information in the date
field is VERY important.
