>Description:
Trying to build the "netbsd-3" branch under NetBSD 4.99.1 dies with this
error message:

f="";  for i in elf32-i386.lo elf32.lo elf.lo elflink.lo elf-strtab.lo elf-eh-frame.lo dwarf1.lo i386netbsd.lo aout32.lo elf32-gen.lo cpu-i386.lo ; do  case " $f " in  *" $i "*) ;;  *) f="$f $i" ;;  esac ;  done ;  echo $f > tofiles

It works fine if I either set "CONFIG_SHELL" to "/bin/ksh" or use a slightly
older "/bin/sh" (built from "netbsd-3" or "netbsd-4" branch sources).

>How-To-Repeat:
cvs -d cvs.netbsd.org:/cvsroot checkout -P -rnetbsd-3 src
cd src
./build.sh -u -U

>Fix:
Backout revison 1.75 of "src/bin/sh/expand.c".
