FWIW, the Itanium C++ compiler is based on the Intel C++ compiler, and 
not on the OpenVMS Alpha C++ compiler environment.

Beyond what's listed in the User's Guide for OpenVMS Systems chapter 
Porting to I64 Systems 
<http://h71000.www7.hp.com/commercial/cplus/docs/ugv_port.html> — see 
the references there around "Comma lists are not supported. Their use 
provokes a fatal error.", and the section around "%CXX-E-UNDECLARED, 
identifier "cout" is undefined", and have a look at the couple of 
references to the basic_string class that available there — you'll want 
to lodge any complaints and any enhancement requests with HP or (soon) 
with VSI.
