Wait, wait, step back... this in itself sounds like a problem. Can 
anyone on the list verify that Cygwin's bash is setting these *at all*? 
(Of course, Ken's OP seems to imply he has it at least half working, but 
something smells fishy here...)

Bash is *supposed* to set these behind-the-scenes without your doing 
anything. This seems to be how it works on Linux...

Testing with a Windows console window:
$ echo $LINES

$ echo $COLUMNS

$ export LINES COLUMNS
$ echo $LINES

$ echo $COLUMNS

$ bash
$ echo $LINES

$ echo $COLUMNS

$ echo $C<tab*2>
$CC       $COMMONPROGRAMFILES  $COMPUTERNAME  $COMP_WORDBREAKS
$COMSPEC  $CVS_RSH             $CYGWIN
$ echo $C $C <-- yeah, that's broken too :-)

...and I see the same thing if I ssh in from Konsole (from a Linux box).

I understand why CGF wants this on cygwin-xfree, but I don't think it 
has anything to do with xfree (I will grant they may be more likely to 
have heard of it).
