 Hi there ...
 I am trying to compile geleon 1.2.8 on my SuSE Linux 8.1 box.
 While running configure I got the following lines:
 
   checking X11/extensions/Xinerama.h usability... no
   checking X11/extensions/Xinerama.h presence... yes
   configure: WARNING: X11/extensions/Xinerama.h: present but cannot be compiled
   configure: WARNING: X11/extensions/Xinerama.h: check for missing 
prerequisite headers?
   configure: WARNING: X11/extensions/Xinerama.h: proceeding with the 
preprocessor's result
   configure: WARNING:     ## ------------------------------------ ##
   configure: WARNING:     ## Report this to address@hidden ##
   configure: WARNING:     ## ------------------------------------ ##
   checking for X11/extensions/Xinerama.h... yes
 
 Xinerama.h itself does not include other headers. :-(
 
 How can I help you?

Hi,

You can help by reporting this failure to the Galeon maintainers.
With the following piece of Autoconf documentation.  Thanks!
