c++ errors in gcc 3.3 prelease 2?

[Andrew Pinski]

This is not really a failure per say but a fall out do to a change in  
bison.

Both syntax and parse error are the same, this can be fixed by changing  
the test to include both forms of the error: "parse|synax error".

The code is invalid so it cannot be able to compiled but the compiler  
should not ice.

Thanks,
Andrew Pinski
