Don't trust comments in the sanity check, use the source, Luke!

That flag is only set when CVS is running as a server (e.g., pserver). 
In that case, the very idea of a "home" directory is pretty nebulous. 
Like I said, it works fine on other Unix and Unix-like systems:

        bash-2.02$ export HOME=/tmp/foo
        bash-2.02$ cvs login
        Logging in to :pserver:address@hidden:2401/public/CVS
        CVS password:
        cvs login: warning: failed to open /tmp/foo/.cvspass for reading: No 
such file or directory
        cvs [login aborted]: could not open /tmp/foo/.cvspass for writing: No 
such file or directory

It seems that cygwin is somehow special-casing getenv("HOME") rather
than just returning the value set in the environment like one would
expect.
