[ECOS] errors in building ecos network tests

[pyxue]

Hi, I meet a problem in building network tests. 
I can only build the fist test, which is something about testing  buffer,
and it runs well too. but to  the second , I meet the problem of
"relocation truncated to fit:R_MIPS_GPREL16 time" . 
The error message refer to the line "if(ru_counter >=RU_MAX || time.tv_sec 
> ru_reseed)"
I consider something is wrong with the definition of time.
The following context is the definition of time:
extern volatile struct timeval time
struct timeval{
                long tv_sec;
                long tv_usec;
}

My host is NT4.0 and the target is vr4300, can someone tell me what is
wrong now?
