--site option

[Ben Elliston]

My generated configure script recognises a --site option:

-site | --site | --sit)
ac_prev=site ;;
-site=* | --site=* | --sit=*)
site=$ac_optarg ;;

However, $site is never referred to. What's the purpose of this? Is
it meant to be a command line analogue for the CONFIG_SITE environment
variable?

Cheers, Ben

If memory serves, there used to be a -site option in all 'configure' scripts.
That feature was removed decades ago, and the above code attempts to cater to
people who were invoking 'configure' with the old option.

Ah, OK, thanks. The option must be old -- it's not even in Autoconf
2.10!
