Various flames

[Richard M. Stallman <RMS at MIT-AI>]

    I am very upset by your recent patches which affect the file system.
    First, they have no place in the patches for System.  For instance,
    78.34 won't load in an enviroment which does not have your file system
    stuff in it.
This is a patch to a file which is part of the standard world load.
What environment won't it load into?  I made the patch on a random Lisp
machine which did not have anything special loaded into it, and it
worked there.

Perhaps it only works in MIT systems.  I don't know the right way to
conditionalize a patch that is for SYSTEM at MIT, only.
