9 stable is in worse shape than current ! Some fixes.

[Julian H. Stacey]

Hi freebsd-stable at freebsd.org,

9 stable is a lot worse than current to build !
Suprising as in the old days it used to be the other way, but on
2 current boxes here I have very little trouble building, (usually
just new includes needed), whereas 9 stable is lots of trouble:

My env.:
	9-stable ( .ctm_status src-9 1374, .svn_revision 277102 )
	(within a prison with 9.2
		FreeBSD 9.2-STABLE FreeBSD 9.2-STABLE #3 r264390:
		Sun Apr 13 12:16:37 CEST 2014
		:/usr/obj/usr/src/sys/GENERIC  amd64 )
	The jail has all ist own binaries, not shared with prison...
	& with nothing in /etc/make.conf except 	NO_FSCHG=YES
	To ease debugging of include paths after interrupted dependent
	makes etc, I did not use a /usr/obj/ (though I do normally).

Problem 1 - Solved:
 9-stable default : cc -v # gcc version 4.2.1 
 11-Current default : cc -v # clang version 3.5.0
 In both cases my boxes use Unchanged default cc.
 It seems developers only tested make world & bsd.sys.mk with clang !

 These errors:
  ===> lib/libfetch (all) SSL
        cc1: warnings being treated as errors
        common.c: In function 'fetch_ssl':
        common.c:808: warning: unused parameter 'URL'

  ===> lib/libmagic (all)
        cc1: warnings being treated as errors
        /usr/src/lib/libmagic/../../contrib/file/src/apprentice.c:942: warning: 'apprentice_list' defined but not used

 Can be avoided by applying this emergency patch-out:

Problem 2 - Not Solved
	# ===> lib/libarchive (all)
	#       /usr/src/lib/libarchive/../../contrib/libarchive/libarchive/archive_hash.h:129:20: error: sha1.h: No such file or directory


Problem 3 - Not Solved
 ===> libexec/telnetd
	... undefined reference  ...


Problem 4 - Not Solved - in /etc/src.conf I had to add:

	WITHOUT_ATM="YES"               # sbin/atm/atmconfig
	WITHOUT_OPENSSL="YES"
	WITHOUT_RESCUE="YES"

	# WITHOUT_BSNMP="YES"           # lib/libbsnmp/libbsnmp
		# No longer need to avoid that, maybe fixed by bsd.sys.mk.diff

Anyone else see these problems ?  Suggestions ?

These observations are on a production server I've temporarily
patched out from active service, but I want to return it soon,
so unless there's some quick fixes, I'll have to down grade it
from 9-stable to 9.3-RELEASE, cos I dont care about things like
atm, but I do need ssl & ssh.

Cheers,
Julian
