Thanks Stephen,  I was trying to force errors in kernel builds by
doing these kinds of define changes while doing my delete tests.

But I was not doing userspace builds, however....

Looking back at the changes I've made, the only thing similar that
I can see is the ipx.h changes:

diff --git a/include/linux/ipx.h b/include/linux/ipx.h
index 3d48014..8f02439 100644
--- a/include/linux/ipx.h
+++ b/include/linux/ipx.h
@@ -38,7 +38,7 @@ struct ipx_interface_definition {
 #define IPX_FRAME_8022		2
 #define IPX_FRAME_ETHERII	3
 #define IPX_FRAME_8023		4
-#define IPX_FRAME_TR_8022       5 /* obsolete */
+/* obsolete token ring was	5 */
 	unsigned char ipx_special;
 #define IPX_SPECIAL_NONE	0
 #define IPX_PRIMARY		1

Please let me/netdev know if the above also happens to trigger any
sort of userspace fallout, and we'll fix it up ASAP.

Thanks,
Paul.
