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 ? =)

When you call a function with a double parameter, do you put double in there? Of course not, because it won't compile.

Function prototypes are not function calls.
