[exim-dev] Script errors

Again this is on FreeBSD4 so I'm not sure if anyone wants/cares to
fix this..

exicyclog gives me:

expr: syntax error
[: -lt: unexpected operator
[: -gt: unexpected operator
expr: syntax error
[: -le: unexpected operator

make install gives me:

[..]
cp exim_checkaccess /tmp/exim-4.72

expr: syntax error
[: -ne: unexpected operator
Installing default configuration in /tmp/exim-4.72/configure
[..]

A quick look seems to point to use of '--' that was added to
usage of expr.
