The function atexit() will let you define a hierarchy of functions to 
execute when the program is exiting either through return from main() or 
a call to exit() (the _exit() function skips atexit processing).

For entry code you will either have to live with executing stuff at the 
beginning of main() or write a custom verstion of crt0.o the startup 
module.
