I would strongly urge not to remove such constructs, but rather to
begin your script with the sourcing of init.sh, which ensures the
remainder of the script is interpreted by a sensible shell.
Alternatively, I could have done this:

  test=`echo "$1" |sed 's,.*/,,'`

But that would violate my "don't use backticks" rule, of necessity,
since $(...) probably doesn't work in such an old interpreter. So at
first, I was inclined to include this line at the top:

  . "${srcdir=.}/testsuite/init.sh"

But there's an even better solution:
