Here is one suggestion:

#include <string.h>

char *strtok_r(char *str, const char *delim, char **saveptr)
{
    char *token;
    if (str)
        *saveptr = str;
    token = *saveptr;

    if (!token)
        return NULL;

    token += strspn(token, delim);
    *saveptr = strpbrk(token, delim);
    if (*saveptr)
        *(*saveptr)++ = '\0';

    return *token ? token : NULL;
}
