#include <stdio.h>
#include <string.h>

int main() {

    char r[512];
    strcpy(r, "Hello world, how are you?");

    char *d = r+2;  /* let d point on 3rd character in r */

    printf("r=%lx\n", (unsigned long)r);
    printf("d=%lx\n", (unsigned long)d);

    return(0);
}

1) on gcc version 4.1.2 20060928 (prerelease) (Ubuntu 4.1.1-13ubuntu5)
   compiled well and d points to 3rd character as i expected

2) on gcc version 2.95.2 19991024 (release), which is an older UNIX-like system, namely
   IRIX/Indigo system, i got these errors:

t.c: In function `main':
t.c:9: parse error before `char'
t.c:12: `d' undeclared (first use in this function)
t.c:12: (Each undeclared identifier is reported only once
t.c:12: for each function it appears in.)
------------------------------

My question is: Why do i get these errors on IRIX/Indigo and if it has something to do with C / C++ difference
I'll appretiate your help (and my friends too) ...
