sys/kern/uipc_syscalls.c

cscope is your friend.

Bad assumption.  Depending on the compiler, __P either returns the
argument passed to the macro or '()'.  This is because pre-ANSI C
didn't support function prototypes.

    pre-ANSI

	int foo();

    ANSI

	int foo(char *, int *, int, int);

Again, cscope is your friend.
