re: Autoconf build targets

   Looked like a bourne shell to me. Default root shell is /bin/csh on 
   FreeBSD, but I believe /bin/sh is basically the same as ash. 
   Interestingly, MAKEDEV fails to work with bash but works fine with ash.

i'm not sure about freebsd, but netbsd has used ash in /bin/sh
for a Long Time.  i even thought the debian one was based on the
netbsd sources but i could be wrong on that point.

   sh is one of the tools it needs to build the source. There are several 
   others:
   
   skaro:/# ls /usr/bsd/bin
   byacc       gcov        kas       kgdb      kranlib   make       patch  yacc
   colldef     gensetdefs  kc++filt  kld       kreadelf  mkdep      sh 
   yyfix
   compile_et  install     kcc       knm       ksize     mknod      tcsh
   csh         kaddr2line  kcpp      kobjcopy  kstrings  mktemp     tsort
   find        kar         kgasp     kobjdump  kstrip    objformat  xargs
   
   And yes, all of these are things for which I can't presently substitute 
   the regular versions of these from Debian packages. :(
   
   Several of the tools are there because they have incompatible options to 
     GNU versions. find and install for example. Others are apparently 
   BSD-specific, like gensetdefs or compile_et.

(dunno about gensetdefs, but compile_et is part of kerberos.)


FWIW, in netbsd-current, basically everything is cross buildable from
several platforms (netbsd-current, netbsd 1.5, freebsd, linux,
solaris, maybe more...)  this is possible because we now build "native"
versions of all these tools before building the world.  i heard a
whisper that freebsd is starting to be interested in cross compiling
(it was a reason to ditch perl as part of the base) so maybe they'll
get to that point eventually.  in the netbsd source tree, see both
src/build.sh and src/tools... the former is a frontend script to building
stuff without having to know all the magic variables to set, etc., the
latter consists mainly of Makefile's to build native versions of tools,
eg, for lex we have:

#       $NetBSD: Makefile,v 1.3 2001/11/14 22:13:40 tv Exp $

HOSTPROGNAME=   nblex
HOST_SRCDIR=    usr.bin/lex

.include "${.CURDIR}/../Makefile.host"

scan.c:
	echo '#include <initscan.c>' >$@



(those ktools things scare me... i wonder why they need special
kernel wrappers/programs for all the toolchain bits...but i think i'd
be scared by the answer :-)
