Yep. This slipped through because I happen to have reconfigured my /bin/sh to point to bash (frrom Ubuntu's default of dash) because of an issue with a product installation script. This shouldn't have been a problem if bash's POSIX mode was strict about rejecting == but bash doesn't seem to be strict about this. Anyway, I have reverted /bin/sh to refer to dash so hopefully I won't be caught by this in future. jon.
