Try this:

pawn Код:

forward IsPlayerCloseToMarker(playerid,Float:markx,Float:marky,Float:markz,Float:distance);
public IsPlayerCloseToMarker(playerid,Float:markx,Float:marky,Float:markz,Float:distance) {
    new Float:markx,Float:marky,Float:markz,Float:distance;
    if(GetDistanceBetweenPlayerToPoint(playerid,markx,marky,markz) < distance) { return 1; }
    else if(GetDistanceBetweenPlayerToPoint(playerid,markx,marky,markz) > distance) { return 0; } 
    return 0;
}

It should remove those 2 warnings.
