Oregon Software's Modula-2 compilers (Suns, VMS, 68K machines) all flag at
compile time code that tries to change the control variable, pass it as a
VAR parameter, etc.

The correspondent indicated that any compiler that didn't perform these
checks was not really Modula-2.  Is there really a M-2 standard that
compilers must meet (which of Wirth's books does it conform to - the 4th
edition of "the" M-2 book just came out, with a few more changes to the
language)?
