C strange warning.

http://pastebin.com/3js28CTR
$> gcc main.c
If tata(char|short|float c) => warning
If tata(int|long|double c) => nothing

Does somebody could explain why exactly ? =)

If you change the prototype to (), you won't get any warning or error for existing function calls that send in an argument.

Yes, but that's the C commitee's fault, just because they want 30-year-old shit code to still be compilable today.
