Any sh that does not support $((3+5)) is broken, and should
not be made /bin/sh on Debian systems.
IEE Std 1003.2-1992
Section 3.6.4 Arithmetic expansion, lines 491-509
Requires that the $((expression)) be supported. If you know of
any shell masquerading as a potential sh replacement that does not
support this, we shall appreciate a bug report, and possibly a report
to this list.
POSIX compliance is a stated goal for us.
