[libXext] configure should check whether `X11/Xauth.h' is present?

Hi!

I've been playing with libXext and I've noticed that it does not build
if libXau's header files are not installed. Here's the output from
`make' command:

  gcc -DHAVE_CONFIG_H -I. -I. -I.. -g -O2 -MT XSecurity.lo -MD -MP -MF

Maybe configure script should check whether Xauth.h file is present in 
the system?
