To underline this with some numbers (I assume you mean the 
demo/text/hello.pp which only contains a mere "Writeln('Hello World')" 
and no additional units; all tests on x86_64-linux with 3.3.1):

- FPC compiled as is: 388976 B
- FPC compiled with full smartlinking: 55920 B
- FPC compiled with C linkage: 388760 B
- FPC compiled with full smartlinking and C linkage: 56792 B

(gotta admit, the last one surprised me though ^^')

Regards,
Sven
