It seems to be something specific to cygwin -- that works fine on other
Unix and Unix-like systems.  You'll need to find someone with more
intimate knowledge of cygwin and the cygwin port of CVS to figure out
what's going on.  For this specific issue, you can set $CVS_PASSFILE to
work around the problem.
Hi, a tried to check this a little bit.
A quick grep for "getpw" as well as for "HOME" through the sources reveals something different;
in src/sanity.sh, it says explicitly:
# CVS looks at the home dir from getpwuid, not HOME (is that correct
         # behavior?), so this is hard to test and we won't try.
No, this is not correct behaviour.
In a few Changelogs, it seems this has been touched multiple times.
In src/filesubr.c, function get_homedir, using $HOME depends on the flag !server_active - while I didn't dig into this deeper and don't know when exactly this flag is set, it does not look proper and I suspect this to be the cause of the problem
Kind regards,
