Do this :

(if (eq window-system 'w32)
    (progn
... your functions here for Microsoft Windows ...
))

window-system is a function and returns the name of the window system.

system-type is a variable. Do C-h v system-type RET to have the list of supported system-types for your case :

From the help :

  `gnu'          compiled for a GNU Hurd system.
  `gnu/linux'    compiled for a GNU/Linux system.
  `gnu/kfreebsd' compiled for a GNU system with a FreeBSD kernel.
  `darwin'       compiled for Darwin (GNU-Darwin, Mac OS X, ...).
  `ms-dos'       compiled as an MS-DOS application.
  `windows-nt'   compiled as a native W32 application.
  `cygwin'       compiled using the Cygwin library.
Anything else (in Emacs 23.1, the possibilities are: aix, berkeley-unix,
hpux, irix, lynxos 3.0.1, usg-unix-v) indicates some sort of
Unix system.

You can do this:

(if (equal system-type 'windows-nt)
    (progn
         (... various windows-nt stuff ...)))
(if (equal system-type 'darwin)
    (progn
         (... various mac stuff ...)))

What I do in my .emacs is set a variable (I call it this-config) based on machine type and name. Then I use the same .emacs everywhere.

Using this code, I can pull the machine name out:

(defvar this-machine "default")
(if (getenv "HOST")
    (setq this-machine (getenv "HOST")))
(if (string-match "default" this-machine)
    (if (getenv "HOSTNAME")
        (setq this-machine (getenv "HOSTNAME"))))
(if (string-match "default" this-machine)
    (setq this-machine system-name))

You can then set this-config based on system-type and/or machine name.

Then I use this code:

(cond ((or (equal this-machine "machineX")
           (equal this-machine "machineY"))
       (do some setup for machineX and machineY))

Edit: system-type returns a symbol, not a string

My emacs says darwin, which is the name for the open OS that OSX is built on. To see the values do a describe-variable on system-type.

Note that the mac also has several possible window types so you might need to make more decisions.
