[Bug c++/14324] New: Muliiple static definitions are not unique

["gary at mlbassoc dot com" <gcc-bugzilla at gcc dot gnu dot org>]

Using gcc-3.4-20040225

If there are multiple occurrences of static variables with the same name 
(different scopes of course) inside a function marked extern "C", then the
names are not mangled nor made unique.  The following function demonstrates
this:

void fun1(void)
{
    do { static int xyz __attribute__((unused)) = 1; } while (0);
    do { static int xyz __attribute__((unused)) = 2; } while (0);
    do { static int xyz __attribute__((unused)) = 3; } while (0);
}

This generates the following:
        .align 2
        .type   _ZZ4fun1vE3xyz, @object
        .size   _ZZ4fun1vE3xyz, 4
_ZZ4fun1vE3xyz:
        .long   1
        .align 2
        .type   _ZZ4fun1vE3xyz_0, @object
        .size   _ZZ4fun1vE3xyz_0, 4
_ZZ4fun1vE3xyz_0:
        .long   2
        .align 2
        .type   _ZZ4fun1vE3xyz_1, @object
        .size   _ZZ4fun1vE3xyz_1, 4
_ZZ4fun1vE3xyz_1:
        .long   3
        .section        ".text"
        .align 2
        .globl _Z4fun1v

Whereas the same function, marked extern "C" generates this:
        .align 2
        .type   _ZZ4fun1vE3xyz, @object
        .size   _ZZ4fun1vE3xyz, 4
_ZZ4fun1vE3xyz:
        .long   1
        .align 2
        .type   xyz, @object
        .size   xyz, 4
xyz:
        .long   2
        .align 2
        .type   xyz, @object
        .size   xyz, 4
xyz:
        .long   3
        .section        ".text"
        .align 2
        .globl fun1v

This of course generates an assembly error.

This used to work - at least as recently as GCC-3.3.3
