OK, I used the crt0.S and the proc.c that is included in the newlib to 
create a standalone without lib support, but I think that the library 
offers support for basic operations like the multiplication. When I 
wrote the classical factorial program it told me to include the function 
__mulsi3. So, it will depend on the program to modify or not the 
standard compilation/linking process.

Thanks for the answer.
