Mumble ....

We have 3 different scenarios:

1) True *nix systems: host file can be only /etc/hosts, so default =
/etc/host is OK.

2) Native WIN32 systems: host file can be only on win system directory,
different between 9x and NT (Argh !!!), so a default is platform dependent.

3) CygWin systems: host file can be /etc/hosts or/and the same as native
WIN32, what default ?

Scenarios 1) and 2) can be resolved with a new "default" keyword, with
run-time platform recognition.

Scenario 3) Problems comes from the potential existance of 2 different host
file, but i think that this is a very big CygWin bug: static name
resolution on a system environment like CygWin MUST be ALWAYS univocal !
CygWin developers say "Unix use /etc/host, so we have our host file" ...
This is not a reason, now for example, if from a CygWin prompt I type ping
host.pippo.com (using Windows ping) or ssh host.ping.com (using CygWin ssh)
the statically resolved host may be different. This is WRONG.
So, as long this CygWin problem is unresolved, we must choice what default
host file to use, IMO, is better use the same of the OS, in Windows system
directory.
