Not sure which code you got a warning with, but the following doesn't even provoke a warning:

--- Code: ---int main()
{
printf("Hello, world!\n");
return 0;
}

--- End code ---
...

--- Code: ---gcc -o test.exe test.c

--- End code ---

killerbot:
the code I mentioned above (same as yours), I ran from within CB.

Checked full log : seems the following options were added : -Wall -fexceptions (and offcourse a -I to mingw includes)

mitsukai:
this is probally a mingw or GCC extension (as it says in the warning). printf is a built in function, just like vc++ can compile non-standard types as built-in types.

jguarin2002:
Thanks mitsukai.
