The comment is very long, and this is not a check you just enforce a lower boundary.

The _ prefix is preserved for standard-specified things (as per the ISO C standard) IIRC. Please rename.

Setting the
burndelayvariable to0crashes the game. To fix this we can't just setburndelaymin to1because servers that don't have the patch, will just override it, therefore I had to use temp vars like_burndelay = std::max(burndelay, 1);Closes: #177
