The actual problem several of us have been running into and are
pointing out are not that we are moving a pre-ANSI Lisp program to an
ANIS Lisp program.  The the problem is that of the *variabilities* of
existing ANSI Lisp implementations, the insufficient portability made
by ANSI Lisp, etc.

FWIW I've  helped converted large non-trivial programs (e.g.) from K&R C
(actually dialects of K&R C) to ISO C.  I've also been helping 
the existing GCC's ISO C soure base to be *compilable* with ISO C++.
The task is non-trivial, but OK.  Because there are *usefully usable*
C and C++ standards.

How do you qualify the one who refuses to listen and understand what
people are reporting as the problem?
