Hmmm, I worked on a System/36 for over a decade, but I wasn't aware of a C,
much less a C++, compiler available for it. Its operating system (SSP) was
written in Assembler.

Subject: Interesting - Duqu Trojan written in IBM SYS26, SYS38, OS400 C?

The blog post from Kaspersky Lab is already filled with comments guessing at
the possible programming language used. Check them out for
yourself: The Mystery of the Duqu Framework.

One comment from user As400tech, who registered his account with Kaspersky
Lab today, looks particularly promising:
That code looks familiar
The code your referring to .. the unknown c++ looks like the older IBM
compilers found in OS400 SYS38 and the oldest sys36.
The C++ code was used to write the tcp/ip stack for the operating system
and all of the communications. The protocols used were the following
x.21(async) all modes, Sync SDLC, x.25 Vbiss5 10 15 and 25.
CICS. RSR232. This was a very small and powerful communications framework.
The IBM system 36 had only 300MB hard drive and one megabyte of memory,the
operating system came on diskettes.
This would be very useful in this virus. It can track and monitor all
types of communications. It can connect to everything and anything.
