Yep, that seems to have got it.

Now the problem is that tags don't seem to understand new Fortran90
constructs - I have some 'pure subroutines' in modules, both of which are
new, and xemacs comes up with 'no tags containing blah'.

Emacs does the same thing -- I noticed the etags.el that comes with emacs
is quite a lot bigger than xemacs's (and seems already to have the
case-fold thing happening). Not knowing how etags works, maybe this is
etags's fault rather than {,x}emacs's etags.el?
