  "I probably don't know what I'm talking about."
System: NetBSD socrates 1.6ZI NetBSD 1.6ZI (socrates) #2: Thu Jan 29 19:56:35 CST 2004  root@socrates:/usr/netbsd/current/src/sys/arch/amd64/compile/socrates amd64
Architecture: x86_64
Machine: amd64
	It seems that most of the LISPs in pkgsrc have more or less serious
	issues when you try to compile them on the AMD64.  I'm coming to
	suspect that inveterate LISPers have spent too much time in typeless
	environments as they tend towards rather sloppy confusion between
	integers and pointers.

	For my purposes, I was looking for a non-GPLed, non-LGPLed LISP, which
	ruled out the only ones that *worked* (xemacs and now emacs).  Almost.
	TinyScheme compiles with just a few warnings about abuses of
	pointers and integers.

	Because of the lack of LISPs (outside of EMACSen) that work on AMD64,
	I felt that this was a serious problem.  (^&
	Try to recompile tinyscheme from pkgsrc on an AMD64.  (Or probably any
	box that has different integer and pointer sizes.)
	I patched scheme.c and provide the following which should REPLACE the
	old patch-ab file.  Basicly it involves a few cases of changing {int}
	to {long}.  There is a warning that I did not see fit to fix about
	the SUN_DL symbol being redefined.  (As far as I can tell, the code
	only cares *if* it is defined.)
