Sorry for the confusion.  I wasn't expecting people to psychically
determine if anyone else had problems.

While I appreciate the inclusion of a simple test case, it's always best
if the simple test case actually compiles.  Since C++ doesn't accept the
strange characters as whitespace, the test case did not compile.  I did,
obviously, work around the problem but its always best to put in as few
barriers as possible if you want help.  Inclusion of illegal characters
in a source program program is a barrier.
