	Jochen, could you explain it better, please?
	
	1 - I didnt find a "-r" option in gcc manual (from FSF)
	What does "-r" do? 
	I know "ld" have a "-r" option. Why can you use it for gcc?

	2- My module must use math functions sin and cos ( libm ), 

	I followed yours instructions and I built a module
of 950 Kb:
	gcc -nostdlib -static  -r -o rt_serbidir_sim.o
rt_serbidir_sim_obj.o rt_control_obj.o mime-crc/mime-crc.o -lm -lc

	I did not need linking with lgcc.
	Is this size really necessary? 950Kb for sin and cos?

Thanks in advance, sorry by my poor english...
