shell portability question

I'm in the process of converting libtool to use autom4te to generate 
its scripts, but now a test I inherited from Gord is failing...

The failing test case says:

# Check that break and continue aren't misused in our portable shell 
scripts.
$EGREP -n '[^    ]=[^    ].*(break|continue)' $scripts \
  && func_fail "cannot use \`break' or \`continue' on the same line as 
an assign
ment"

But AS_SHELL_SANITIZE says:

# Find who we are.  Look in the path if we contain no path at all
# relative or not.
case $[0] in
  *[[\\/]]* ) as_myself=$[0] ;;
  *) _AS_PATH_WALK([],
                   [test -r "$as_dir/$[0]" && as_myself=$as_dir/$[0] && 
break])
     ;;
esac

Who is correct?

Cheers,
        Gary.
