---------------------------------

Hi ran into this issue also when parsing a negative int64. I dont know why the axutil lib
does not use standard C lib but here is a fix that i implemented for my project:

#include <stdlib.h>

AXIS2_EXTERN int64_t AXIS2_CALL
axutil_strtol(
    const char *s,
    char **endptr,
    int base)
{
    int64_t n;

    n = 0;
    n = strtoll( s, endptr, base );

    return n;
}

> you will know this problem when you look at this function, if input parameter s is '-1234567',
then first char is '-',  the for loop will breaks, the this function return 0 to you.
