Why? int main() is fine in C99 (and it even says to in those slides).

It is illegal in C11 however.

No it's not, at least not in the current draft. Section 6.7.6.3, paragraph 14:
"An empty list in a function declarator that is part of a definition of that function specifies that the function has no parameters."

IIRC, the standard demanded that main be one of two signatures: int main(void) or int main(int, char **) only. That would be in line with page 24's "you should use int main(void) - because the standard says so", provided the PDF is right.

I disagree. I think that -Wall should print many more warnings than it does.
