To clarify, we've got a pile of config files available:

dix-config.h            All server files need this
kdrive-config.h         All kdrive files need this
xorg-config.h           Xorg needs this
xwin-config.h           Xwin needs this

xorg-server.h           No server file can use this

Anything under hw/xfree86 should include xorg-server.h
Anything under hw/xwin should include xwin-config.h.
Anything under hw/kdrive should include kdrive-config.h

Everything else should include dix-config.h

Nothing should include xorg-server.h

Might be better to stick this check in os.h or misc.h as those are both
included by most of the files in the server. But, this seems like a good
safety measure.

I ran through the entire server source code and verified that every
single file depends on dix-config.h.

Then, I went and looked for files including xorg-server.h and found a
few. I've sent out a patch which fixes those and adds a check in
xorg-server.h.in to make sure no-one ever does it again.
