[Bug c/38047] New: -Wredundant-decls does not take scope into account

["paulf at free dot fr" <gcc-bugzilla at gcc dot gnu dot org>]

/* red.c */
void foo(void)
{
    extern int x;
    /* use x */
    x = 1;
}

void bar(void)
{
    extern int x;
    /* use x */
    x = 2;
}

gcc -Wredundant-decls -c red.c
red.c: In function 'bar':
red.c:10: warning: redundant redeclaration of 'x'
red.c:3: warning: previous declaration of 'x' was here

The two "extern int x;" declarations are *not* redundant, and removing either
will cause this code to fail to compile.

Also happens with GCC 4.1.2.
