[lwip-devel] [patch #9072] Add missing include for lwip/sys.h

[Axel Lin]

Follow-up Comment #4, patch #9072 (project lwip):

Hi,

After moving the define of LWIP_RAND() to arch/cc.h.
I still got the build worning without this patch.

In arch/cc.h:
#define LWIP_RAND()                    sys_rand16()

In FreeRTOS/sys_arch.c: the implementation of sys_rand16()
In FreeRTOS/arch/sys_arch.h: Declare sys_rand16()

To avoid the build warning I need to include arch/sys_arch.h.
arch/sys_arch.h is included by lwip/sys.h.

>From the code I don't find other users to include arch/sys_arch.h directly,
thus
include lwip/sys.h.
