Subject: [PATCH] Cross-compile script for the faster gencgc allocator on
 sparc.

(A cross-compile may not have been necessary, but I didn't try it.)

+;;;;
+;;;; This cross-compile script is used for cross-compiling from a
+;;;; 2003-12 solaris snapshot to 2004-01-14 (or so) sources.  This
+;;;; version has a faster gencgc allocator that uses alloc-tn as
+;;;; alloc-tn was intended to be used.
+;;;;
+;;;; It may be possible to make this change without a cross-compile
+;;;; but I did not try it.
+;;;;
+;;;; This is basically a copy of
+;;;; src/tools/cross-scripts/cross-sparc-sparc.lisp.
