I think MacOS Emacs isn't very resilient to customizations for other
platforms that should be ignored.  For example, my



((menu-bar-lines . 1) (font-backend . "xft") (font . "Bitstream Vera Sans Mono-10.5") (tool-bar-lines . 0))

But `M-x new-frame' causes emacs to report "no font backend available"
without opening a new window.

This is no different than setting (font-backend . "garbage") on any
platform. If you have platform specific settings in your .emacs which you want to share between platforms, then you need to make them conditional.

We could make it easier for the users by ignoring invalid font- backends,
so a single setting can work on all platforms.

Yes, that would be a start, and it's what I had in mind. Conditional things don't mesh too well with using the customization interface. If you are going to let people set up platform-specific things in customize, the first step would be to ignore them if they don't apply, and the next step would be to support platform-specific customizations directly, so I could use one font-backend on Linux and another on, say, MacOS.
