Iterate macro on Symbolics

[Michael Sokolov <sokolov@victoria.media.mit.edu>]

	I got the following error during (pcl::compile-pcl) on a
Symbolics running 7.1:

For function optimize-iterate-form,
Error: The second argument (value) to sys:signed-immediate-operand,
231, was of the wrong type.  The function expected a small signed
operand.
	Arg 0 (compiler:opcode): 67
	Arg 1 (compiler:value): 231


	This is a little beyond me, but I was just wondering if anyone
had had any success compiling the new (7/7/88) PCL in Symbolics 7.1?
