From e2f6ebd3f2969753e4ffc337ce5fb6cdf9d74775 Mon Sep 17 00:00:00 2001

Subject: Fix up breakage resulting from flipping the sense of some defines. 
 Change from defining things to "0" in the disabled case to outright
 undefining them, lest code that does an "#ifdef FOO" get inadvertantly
 triggered.  Remove now unneeded lines from Rules.mak which makes the command
 line smaller and avoids redundancy (since this stuff is now pulled in via
 features.h).  -Erik
