Sorry, but at this point I'm confused:

- Cygwin use Windows host file, but before now I thought that it use
/etc/hosts.
- /etc/host is (must be ?) a symlink to the Windows hostfile.

But, I have just installed Cygwin, and there is no /etc/host symlink or
file, so you say that I must make this symlink ? But if this true, how many
users make this symlink ?
Why this is not made from Cygwin setup ?

But also if the hostfile symlink it's not made automatically from Cygwin
setup ....
