The word you're looking for is "POSIX". Seriously, if it were bashisms,
or any other modern shell, it would be using $(( ... )) instead of
messing with expr(1).
Instead, Tony forgot that $(...) is not in Solaris /bin/sh, despite
being in POSIX. Hey, it's only been 19 years since
"IEEE Std 1003.2-1992". Give it a few more years and we can celebrate
the 20th birthday of Solaris finding a way to claim POSIX compliance by
only providing a POSIX shell as /usr/xpg4/bin/sh instead of /bin/sh.
I'll copy the same "re-exec self using a POSIX shell" hacks I wrote for
the "lookups-Makefile" script.
