libXext help with bug solution.

[Alistair Leslie-Hughes]

Hi,

While triaging bugs, I came across this one.

https://bugs.freedesktop.org/show_bug.cgi?id=14723

The basic issue is warnings during the compile.
The options
1. Add prototypes (like the patch attached to the bug) to silence the 
warning.
2. Remove the functions, since they appear to be unused.

Any Ideas?

Best Regards
