Mmmm I'm afraid I'm unable to keep my custom file free of my
platform-specific stuff. I've just seen this behavior:
1. I remove the `default' and `variable-pitch' lines from my custom file.
2. I exit Emacs, start it again and verify that my custom file doesn't
have the lines I removed.  Note that this session has loaded my init
file, which first loads my custom file and then makes the
platform-specific customization (in that order).
3. I do some customization (change the box-width property of the
`mode-line' face, for example), and save it (C-x C-s).
4. I reopen my custom file and see that the two lines I removed in #1
have been reinserted.

Changing the order (first do the platform-specific customization and
the load the custom file) doesn't help.  The custom file is
regenerated (when I save any customization) entirely, including the
`default' and `variable-pitch' faces.
