That's what I did, but it doesn't help for the non-standard usage of
/usr/bin/time (-f option).  They even explicitly used /usr/bin/time
rather than bash's builtin.

Did you try?  Maybe my version of pdksh is just too old, but it
doesn't grok that $((I--)) construct either.

OK, just installed ksh93, it appearently understands it.

Still, I don't see a real need for this in CSiBE as it would be simple
to replace it by the standard Posix arithmetics syntax, or even more
portably by the use of expr(1).  The time -f thing is a bit harder to
do (in particular given that bash's time(1) builtin behaves different
that the Posix time(1)).
