[krbdev.mit.edu #1707] src/config-files/krb5.conf does not specify kdc for ATHENA.MIT.EDU

["Jeffrey Altman [Kermit Project]" via RT]

Checking the Makefile.src file produced during the grafting of the krb5
module into the pismere build tree it appears that only

  KRB5_USE_DNS=1

is defined.  This means that KDC Lookups are off by default on Windows.
I can change this in the Perl scripts that perform the graft.  However
it would be preferable to have one setting that would be picked up by
both Leash and krb5.

P.S. - I think it is appropriate for non-zero default settings to still
be specified in the krb5.conf file (perhaps with a comment).  The 
assumption
is that missing values are "false".
