Because that's not how it works :-)  It doesn't search for the file, it
just checks for it.  So if you had:

  #include <xorg/xorg-server.h>

That would work.  The configure script is probably broken in this case
not to look for the appropriate pkgconfig file.  That usually controls
the -I flags for a build.  For instance you can do:

  $ pkg-config --cflags xorg-server

And see where things are on your system.  On my Ubuntu 11.04 system that
returns:

  -fvisibility=hidden -I/usr/include/xorg -I/usr/include/pixman-1
