Details:

How about adding the following to lwip/arch.h? Would it be OK to use c99
headers?

/* Define generic types used in lwIP */
#ifndef LWIP_NO_STDINT_H
#include <stdint.h>
typedef uint8_t   u8_t;
typedef int8_t    s8_t;
typedef uint16_t  u16_t;
typedef int16_t   s16_t;
typedef uint32_t  u32_t;
typedef int32_t   s32_t;
#endif

/* Define (sn)printf formatters for these lwIP types */
#ifndef LWIP_NO_INTTYPES_H
#include <inttypes.h>
#define X8_F  "02"PRIx8
#define U16_F PRIu16
#define S16_F PRId16
#define X16_F PRIx16
#define U32_F PRIu32
#define S32_F PRId32
#define X32_F PRIx32
#define SZT_F PRIuMAX
#endif
