5620 DMD SGS bugs

[Doug Gwyn <gwyn>]

I am having a hilarious time bringing up the 5620 DMD SGS under
4.2BSD (using the BRL UNIX System V Rel. 2 emulation to save work).
It seems that the sources were developed for UNIX System V Release
1, which did not have "flexnames" and which used different
"portable archive format" and COFF.

Does anyone know what the correct procedure is to build a UNIX
System V Release 1 - compatible "ar" is from Release 2 sources?
PORT5AR or PORTAR?  FLEX=??  ???

"UNIX System V.  From now on consider it standard."  And variable!
