[Bug c++/16337] New: bug defining multiple altivec vectors in same C++ statement

["janis187 at us dot ibm dot com" <gcc-bugzilla at gcc dot gnu dot org>]

When multiple vector variables are defined in the same C++ statement
the compiler doesn't recognize the ones after the first as vectors.
This test case, extracted from g++.dg/ext/altivec-3.C, fails with g++
built from 20040630 sources; I don't currently have a newer compiler to
test with.  The original test has been failing for awhile because of
other problems with variable argument lists, so this problem might not
have been noticed by anyone yet.
                                                                               
                
Test case:
                                                                               
                
#include <altivec.h>
                                                                               
                
vector signed int foo (void)
{
    vector signed int v1 = { 1, 2, 3, 4 };
    vector signed int v2, v3;
    vector signed int v4;
    v2 = v1;
    v3 = v1;
    v4 = v1;
}
                                                                               
                
ouput:
                                                                               
                
madcow% $GXX -c -maltivec bug.C
bug.C: In function `int __vector__ foo()':
bug.C:9: error: cannot convert `int __vector__' to `int' in assignment
                                                                               
                
This is using a biarch powerpc64-linux GCC.  I think this is a recent
regression on mainline.
