[lwip-users] [lwip] Compiler name conflict

[Robert]

I am using lwIP with the "NO_SYS" method.  In the header file sys.h, there 
is a structure and a macro with the same name: namely "sys_timeout"  For 
now I have put in preprocessor statements as a workaround, it seems that 
the macro is not even needed although I have not studied this in detail 
and there are a couple of function calls in ethernetif.c.  However 
ethernetif.c does not appear to be needed in my project.  Perhaps it is 
only used when the NO_SYS option is off.  

My compiler cannot deal with these two things having the same name.  
Perhaps other compilers have seperate name pools for functions & 
structures. Could either the structure or the function be renamed? Or is 
there a reason they need to be named the same?


--------------------------------------
#if NO_SYS

/* For a totally minimal and standalone system, we provide null
   definitions of the sys_ functions. */
typedef u8_t sys_sem_t;
typedef u8_t sys_mbox_t;
struct sys_timeout {u8_t dummy;};

#define sys_init()
#ifndef EZ80            // struct & #define with same name
#define sys_timeout(m,h,a)
#endif
#define sys_sem_new(c) c
#define sys_sem_signal(s)
#define sys_sem_wait(s)
#define sys_sem_free(s)
#define sys_mbox_new() 0
#define sys_mbox_fetch(m,d)
#define sys_mbox_post(m,d)
#define sys_mbox_free(m)

#define sys_thread_new(t,a)

#else /* NO_SYS */
