[PATCH] Fix configure.ac to not to treate [ ] as quotes when using them in case

[Roy Marples <roy@xxxxxxxxxxxx>]

Hi list.

Attached is a patch to fix configure on FreeBSD.
This is needed as it uses a shell case statement to test for specific
FreeBSD versions. When run through autotools, it strips the [ ] bit as
it thinks they are quotes.

This fixes Gentoo bug #188930.

Thanks
