Note that Cygwin has a few oddities that might explain some of the
issues that Mark is experiencing. I've recently been fighting Cygwin in
similar ways.
In particular, if Cygwin's bash.exe (or sh.exe) is used as the gmake
shell, Cygwin detects that it is being launched by a non-Cygwin process
and performs some perturbations of the command line including collapsing
of (unquoted) backslashes. The results are then processed by bash/sh as
UNIX normally would. Try adding "noglob" to the Cygwin environment
variable to see if that changes behavior. The "noglob" option is
documented at http://www.cygwin.com/cygwin-ug-net/using-cygwinenv.html
(though the documentation doesn't explain this option particularly
well). Also, try quoting paths in command lines passed through Cygwin
binaries - doing so affects the extra globbing that Cygwin performs.
I've noticed that the latest Cygwin 1.7 DLL seems to have some problems
with the "noglob" option. There are some command lines I have been
completely unable to get passed through to Cygwin when using the
"noglob" option. I've had to stick to "glob" (the default) and double
escape backslashes for the time being.

The way it works with the Windows shell and Windows echo will not
change.
wait, we already established, that this has nothing to do with shell or echo -
on Windows, GNU make is currently stripping one of 3 backslashes in a command
like this:
Foobar:
perl foobar.pl \\\foobar
and, I think we have established that this behavior is undocumented ( I think Paul is saying it is a bug, and you are saying you are not sure).
It does that only when it does not invoke builtin commands.
