           Product: gcc

On powerpc-apple-darwin9 at revision 175158 g++.dg/ext/altivec-17.C fails with

FAIL: g++.dg/ext/altivec-17.C  (test for errors, line 15)
FAIL: g++.dg/ext/altivec-17.C (test for excess errors)
Excess errors:
/opt/gcc/work/gcc/testsuite/g++.dg/ext/altivec-17.C:15:24: error: invalid
initialization of reference of type 'const simd_type& {aka const __vector(4)
unsigned int&}' from expression of type 'const bool_simd_type {aka const
__vector(4) __bool int}'

which does not match the dg-error "'const simd_type&' from expression of type
'const bool_simd_type'".
The fix should be similar to the one for pr49432 (note that it is likely also a
4.6 regression).

It is, g++.dg/ext/altivec-17.c fails for me on powerpc64-linux with
gcc-4.6-20110617, while it didn't fail with gcc-4.6-20110610.

What would be the "best fix" between the two?
