Download the compiler pack here:
ftp://ftp.compaq.com/pub/products/C-CXX/tru64/cxx/CXX651V38.tar
There is a later CXX651V40.tar in that directory, byt I haven't tried it.
To use binaries from these compiles, target systems need an updated RTL:

Subject: Compaq C++ compiler
I would like to install the latest version of C++ which I have from the
SW products library, namely v6.5, but the sw compatibility says that it
is only supported on Tru64 v5.1 and up and I have v4.0f (with C++ v6.2).  
Why is a compiler dependent on the OS and is there anyway around this, 
e.g. installing RTLs, C libs, etc?  What is the latest version of C++
which is supported on Tru64 v4.0f?  My version is pretty old.
Regards,
Peter
