System: FreeBSD icarus.home.lan 9.0-STABLE FreeBSD 9.0-STABLE #0: Thu May 17 03:03:41 PDT 2012 root@icarus.home.lan:/usr/obj/usr/src/sys/X7SBA_RELENG_9_amd64 amd64
>Description:
	Using WITHOUT_CLANG=true in /etc/src.conf presently results in
	some directories getting created (which probably shouldn't)
	during installworld, as well as some directories not being
	deleted during "make delete-old".

	I should note that this problem began after the llvm/clang 3.1
	preparation import within the past few days.

root@icarus:/usr/src # make delete-old
>How-To-Repeat:
	1. csup to latest sources (a few minutes ago)
	2. Make sure WITHOUT_CLANG=true is in src.conf
	3. Go through usual procedure of building world/kernel and installing them
	4. make delete-old
>Fix:
	Only workaround I know of is, after running make delete-old,
	do the following:

	rm -fr /usr/include/clang

	The other directories in /usr/share/doc get deleted by delete-old, but
	my point is that they shouldn't be created if WITHOUT_CLANG is in use.

 drwxr-xr-x  3 root  wheel  512 May 24 20:54 ../
 
 	Based on what I can tell, the problems is that the following
 	directories are being blindly created during installworld phase
 	with no regard for WITHOUT_CLANG:
 
 	/usr/include/clang
 	/usr/include/clang/3.1
 	/usr/share/doc/llvm
 	/usr/share/doc/llvm/clang
 
 	I imagine whoever did the 3.1 import did not fully modify all
 	the necessary Makefile bits to keep this from happening.  But
 	the 3.0 stuff previously worked fine / did not leave leftover
 	cruft.
