And why would changing the default for VECTORISE_INLINE adversely affect these? I'm trying to understand Frank's statement that "people are bound to stumble over this when they try the released version".  Frank, did you mean the soon-to-be  (ET_2011_10)  released version?  Or the previously released version?  If we change the default to VECTORISE_INLINE = no now, then no-one will run into this problem in the soon-to-be released version.  Since the change to McLachlan didn't exist in the previously released version, it won't affect those.
