Cygwin is a layer on top of Windows, and it uses the Windows machinery to
implement networking. Thus, the question is: where does Windows look for
the "hosts" file? And the answer to that is Windows version-specific, and
could be found by a judicious application of a Google search...

That being said, as a convenience to its users, Cygwin provides a symbolic
link to the Windows hosts file in a standard POSIX place, i.e.,
/etc/hosts. There are also links to other standard files, such as
/etc/networks, /etc/services, and /etc/protocols.

"Cygwin" doesn't care about "hosts". The applications are looking for
it in /etc and it is symlinked to the Windows default file in
%SYSTEMROOT%\system32\drivers\etc\.

<pedantic>The applications (through wsock32.dll) look for it in the
standard Windows place, which is %SYSTEMROOT%\system32\drivers\etc\ on
WinNT/2k/XP and %WINDIR%\ on Win9x. The symlink is for the
users.</pedantic>

Well, I thought some /applications/ were explictly looking and
complaining for the existence of the "most important" files on a Unix
host and this was the reason for the hosts, networks, services and
protocols links.

I am not aware of any. AFAIK (and I should, I participated in the
creation of the package that makes them) the links are purely for user
convenience (and uniformity).

Great!
I am doing a make of mysql and am getting the error:

libmysqld/sql_derived.cc: You are trying to create a symlink on a win32 file
system.
This file type is not supported on this platform.

How do I correctly identify file types to cygwin and
correct this error situation?
Sorry for the bother!
Thanks,
Martin

What has that got to do with /etc/hosts? No application running under
Cygwin knows that /cygdrive/c/WINDOWS/system32/drivers/etc/hosts is in
fact %SYSTEMROOT%\system32\drivers\etc\hosts.
