Hello.
 
	 
 
	I had those errors and warnings when compiling, but I corrected them and now it compiles without problems. I leave the file in case it helps someone.
 
	 
 
	P.D. In ExtendedBG-char.c just change all this lines: 
	 
 
mapif->send(fd, buf, offset);
	To this:
 
mapif->send(buf, offset);
	Regards.
 
	ExtendedBG.c
