EAX library is no longer maintained by Creative and the latest version (5.0) dates back to 2005. The proposal here is to remove it and the associated headers.
I've made a patch available here : https://github.com/MathiusD/joal in 1477-remove-eax-headers
(In reply to Mathieu Féry (MathiusD) from comment #1) https://github.com/JogAmp/joal/compare/master...MathiusD:joal:1477-remove-eax-headers
Yeah, that's find and good!
Merged and done.
