[PATCH]: auth.c (pwcopy): Copy pw_gecos field when build for Cygwin

[Corinna Vinschen]

Hi,

the attached patch is very important for Cygwin. I don't know
how I could have missed that for months now :-( I hope this
can be included in 2.5.1p2.

The pw_gecos field in Cygwin's /etc/passwd contains Windows
specific authentication informations which let NT domain
users logon to a machine without the need to inform the
logon server (sshd in our case) about the name of the NT domain.
As a side effect you can have a different name under Cygwin than
your NT account name.

Unfortunately, without copying pw_gecos this functionality is
completely broken in sshd.

The patch:

Thanks in advance,
