The declaration of a function without prototype is currently silently accepted by sparse but a warning is issued for 'old-style' declarations: ... warning: non-ANSI function declaration ... However, the difference between these two cases is made by checking if a ';' directly follow the parentheses. So: int foo(); is silently accepted, while a warning is issued for: int foo(a) int a; but also for: int foo(), bar(); This last case, while unusual, is not less ANSI than a simple 'int foo();'. It's just detected so because there is no ';' directly after the first '()'. Fix this by also using ',' to detect the end of function declarations and their ANSIness.
