Snapshot report.
================
This is _very_ brief as Alistair G. Crook has already said just about
all that is needed and I haven't finished upgrading yet :-)

I have just a couple of points that may be useful to others who have
not updated their -current in several weeks (I was running Nov20).

Source: tar_files, 12th February 1994, from agate.berkeley.edu
Upgrade from previous -current: yes, Nov 20 tar_files from
agate.berkeley.edu

Machine specifics: 486DX/33, 16MB RAM, 120Mb IDE, 380Mb SCSI, 535Mb SCSI, VGA card

Any problems during make:

Luke Mewburn mentioned a problem with lib/librpcsrv/src I had the same
thing.  I'm sure some one mentioned an alternative solution (I could
find a mail message containing it though).  In anycase Luke's got me
going.  For /bin/sh or ksh uers:

$ cd lib/librpcsrv/src
$ /bin/ls -1 *.x | sed 's,\(.*\)\.x,make -f ../Makefile \1.h,' | sh

I used the following script to build various directories (like
gas,gcc etc).


:
# buildem.sh
cmd="$1"; shift

for f in $*
do
  ( cd $f
    echo "$f ==> '$cmd'"
    eval $cmd
  )
done

example:

cd /usr/src
NOPROFILE=NOPROFILE
NOPIC=NOPIC
NOMAN=NOMAN
LDSTATIC=-static
MACHINE_ARCH=`uname -m`

export LDSTATIC NOMAN NOPIC NOPROFILE MACHINE_ARCH

buildem.sh "make && make install" include share/mk lib/libc gnu/lib/libmalloc 
buildem.sh "make && make install" usr.bin/make usr.bin/tsort
buildem.sh "make && make install" gnu/usr.bin/gas gnu/usr.bin/ld gnu/usr.bin/gcc2

note that the new tsort (newer than Nov20) was needed to be able to
link gcc.

Also with NOPIC set, we don't get a new ld.so so after unseting
LDSTATIC et al and installing the new shared libs you need to make in
ld again.

unset NOPIC LDSTATIC NOMAN NOPROFILE

buildem.sh "make && make install" lib gnu/lib
LDSTATIC=-static
buildem.sh "make && make install"  gnu/usr.bin/ld

Which will install a new ld.so to match the new shared libs -
otherwise nothing happens :-)

Then just back to normal build process. 

Oh yes, and I'm running a new kernel which is now clean except for my
LP_SIMPLE_PROBE hack (below for those that have trouble with
lptprobe())
