	The same "Hello world" program compiled with Eiffel version 2.2-ALPHA, 
post-processed and all optimizations turned on, 
generates an executable of 64671 bytes (53248 bytes stripped) 
on a Sun386i running O.S 4.0.1 where C libraries are dynamically linked.
	On a Sun3 O.S 3.5 with non dynamically linked C libraries, the size of the
generated code is 73728 bytes (57344 stripped).

	The same "Hello world" program written in C 
on a the Sun386i O.S 4.0.1 is 8645 bytes (4408 bytes stripped)
and on the Sun3 O.S 3.5 it is 32768 bytes (24576 bytes stripped).

	Eiffel run-time libraries are currently not dynamically linked
(this might be in Eiffel 3.0).
