I use the following "trick" which was copied from g++ include files.
(Latter are a reasonable starting point for ANSI prototypes for printf
 etc., they are distributed with libg++ I think.)

#if !defined(PROTO_STDIO_H)
#define PROTO_STDIO_H
#include <stddef.h>
#undef NULL
#include_next <stdio.h>
#undef FILE
typedef struct _iobuf FILE;
extern int _filbuf(FILE *);
extern char *tmpnam(char *ret);
extern int fgetc(FILE *f);
extern int fputs(const char *,FILE *);
extern int fputc(int,FILE *);
....
#endif

Technique is to do above then turn on -Wstrict-prototypes and gradually
add them (by hand from man entries) till all the warnings go away.
