red hat 6.2
>Description:
gcc  -O2     -Wpointer-arith  -c a.c
where a.c is:
#include <string.h>

char    a[10], b[10];
void foo(void);
void foo(void) {
    strcpy(a,b);
}

yields:
In file included from /usr/include/string.h:346,
                 from a.c:1:
/usr/include/bits/string2.h: In function `__strcpy_small':
/usr/include/bits/string2.h:419: warning: pointer of type `void *' used in arithmetic
/usr/include/bits/string2.h:427: warning: pointer of type `void *' used in arithmetic
/usr/include/bits/string2.h:432: warning: pointer of type `void *' used in arithmetic
/usr/include/bits/string2.h:437: warning: pointer of type `void *' used in arithmetic
/usr/include/bits/string2.h:439: warning: pointer of type `void *' used in arithmetic
/usr/include/bits/string2.h:444: warning: pointer of type `void *' used in arithmetic

These warnings are quite annoying, because I use strcpy a lot.
