 Does not work. Nothing to see here, move along.
 
 builds only with p9p on linux/386 and amd64; bugged to hell.
+actually, untested on 386, because linux crosscompiling and p9p on not-OSX.
+
 plan9 shit missing completely, asm not ungccfied.
 
 intrusive changes:
 	- pr_strings: assumed 32bit pointer arithmetic: use PR_GetStr() instead of
 	  dealing with it directly; may be ass
+	- global cppdefotomy
 
+
 bugs
 ----
 	- compile with PARANOID -> MSG_WriteByte complains about range error and
-	  exits.  no idea why. (386/amd64)
-	- new game while already ingame -> R_RenderView: called without enough
-	  stack
+	  exits. no idea why. (386/amd64)
+	- new game while already ingame -> front falls off (amd64)
+		. most of the time: exit with R_RenderView: called without enough stack
