I downloaded eqemeu 3.6, and since I use gcc 3.x it doesn't compile.  
Here are three patches to get it to compile with gcc 3.x
(net.cpp is the only one I'm not *sure* about (opening spells.dat) )
Please use these, to advance eqemu to a modern C++ compiler.
Common Patch 
World Patch 
Zone Patch 
And again, here is another patch to bring regen rates to live standards.  Please consider implementing it this time.
