25 years ago, Brian Schenkenberger made a nice hack that made FTAxxx device
UCBs be 64 bytes larger and let privileged processes set the TT_ACCPORNAM field
for those terminals (using the extra space to store the string). I tried
building that code last year on X86 but it failed because the conditional tests
in the VAX Macro source assume 'not Alpha' means 'VAX'.

To try to get it to work, I fudged the architecture tests and fixed some other
things it complained about and amazingly it worked! My goal now it to make a
privileged program that SYLOGIN runs that retrieves SYS$REM_NODE and sets
tt_accpornam. The tt_accpornam zap isn't robust yet because you're supposed to
use LIB$LOCK_IMAGE() now.
