Hi Chris,

I tried linking in the libgcc.a like this:
ahrs.o: ahrs.c
	$(CC) ${CFLAGS} -c -o ahrs_tmp.o ahrs.c
	$(LD) -r -static ahrs_tmp.o -o ahrs.o -L/usr/lib -lm -lc 
-L/usr/lib/gcc-lib/i486-suse-linux/2.95.2 -lgcc
	rm -f ahrs_tmp.o

Now my system freezes when I insert ahrs.o What did I do wrong? 
(I don't get any error messages)
