Please don't go this way.  If someone builds Emacs with --without-x,
they mean it, and we should honor their choice and not cause them any
unnecessary grief.

Also, --without-x could be a result of bad or missing X installation.
For example, I cannot compile with X support on fencepost.gnu.org
(didn't have time to investigate what package is not installed there).

That's not a good idea, either: there's a DOS port of Xlib, which
allows to build Emacs with X support (or at least did that in the
past; I haven't checked that configuration for a very long time).

Basically, checking the OS name shoudl be the very last resort, not
the first one we try.  Let's keep Emacs as clean of ugly OS-specific
hacks as possible.

What's wrong with testing x-show-tip for being fboundp?
