It's a cleanup only in C99 (and C++).  The implicit return 0 was not in 
C90 and indeed GCC goes to a certain extent to only add the implicit 
return 0 in main() in C99 mode or if the target wants this by default 
(only s390 basically).  In fact if you simply compile a program like

int main() { int i = 7; i *= 7; }

without optimization or any other params, it's return value will be 49 on 
i386.  So no, it's not a cleanup at all.


Ciao,
Michael.
