   I have compiled TeX from web2c5.8a.tarZ on both a Sun 4 (SunOS 4.1)
   and a Decstation 5000 (ULTRIX 4.0).  Both pass the trip test.  I am
   using the plain.tex (version 3.0) macro from labrea, and slightly
   modified lplain.tex (version 2.09-February 8, 1990) from labrea.  The
   modifications were as suggested in the web2c package (using a small
   file lplain3.tex that set \lefthyphenmin and \righthyphenmin).
 
Note that lplain.tex and splain.tex have been updated accordingly, the
files are available at least from labrea and Heidelberg.
 
   Now for the problem:  None of the popular "spacing" macros work
   properly (I'm speaking of setspace.sty, doublespace.sty, and
   fnspacing.tex).  They invariably produce errors like the following:
 
    (omitted)
 
Sorry, that's correct behaviour.  This is due to a bug fix in
latex.tex made in May 89.  Previously, LaTeX's check of environment
nesting was not correct.
 
The spacing environments in doublespace.sty use an \endgroup ...
\begingroup trick that messes up the new check mechanism.
 
Probably you should ask the author of doublespace.sty to correct the file.
 
   problem).  Finally, TeX, C Version 3.0 on athena (MIT's big academic
   computing project) does not have the bug.  I don't know what version
   of lplain or plain they have.
 
This means that their version of LaTeX is at least two years old (see
above).
