True.  Many of us have been using it for serious work for months now.  I 
migrated in February or so, and every problem I've had is now months in 
the past.

...and be sure to tell it the new directory name on the *first* run of 
setup-1.7.exe, yea even on the first visit to that screen.  There's a 
point beyond that screen and before you exit setup.exe where you all but 
irrevocably convert an existing 1.5 install to a 1.7 one.  You don't 
even have to actually start the install process; just going deep enough 
into the wizard with it believing you want to upgrade in place is enough.

Personally, I'd just back that directory *and* all the Cygwin registry 
sub-trees up and go ahead with the upgrade-in-place.  Parallel Cygwin 
installs work, but there are annoyances.

Given your evident conservatism (XP SP3), I hope you have a concrete 
reason for upgrading Cygwin.  If not, there's apparently a philosophical 
mismatch somewhere.
