C++ has little OpenVMS system integration.  Outside of OpenVMS message 
files, there seems little else.   Nothing obvious in iostream, for that 
matter.

Specifying RMS file attributes on the fopen() is entertaining when 
working with the strict compilation mode, as the compilations produce 
(expected) diagnostics for the OpenVMS fopen extensions.

Which meant reverting and switching to __USE_STD_IOSTREAMS to get the 
C++98-era "modern" behavior.

C does slightly here with OpenVMS, but still lacks OpenVMS integration.

OpenVMS descriptors, RMS, etc., most of what could be useful for 
working with C++ on OpenVMS is seemingly missing.

Keeping old code mostly-working is certainly valuable, but the 
"Specifying /DEFINE=__USE_STD_IOSTREAM forces the inclusion of the ANSI 
standard version of the iostream header file.

This is the default in STRICT_ANSI mode. Otherwise, the pre-standard 
AT&T-compatible version of iostream is used." is a stinky default for 
anything other than remedial work.
