Hmm... not what I had imagined, but point taken.  This was the only
failure of this kind in the particular configure script I was looking
at, but I shall bear this in mind if I run into anything similar in
future.  Is there a trivial way to specify cumulative flags at
make-time, as opposed to an override?  Not that the latter is a major
issue for me, just means I may have to change a few habits. :)

Also a good point - it's a typical "company policy" thing, rather than
something I personally append.  Nobody's pointed it out before on other
lists, but you're right.  I might have a word and see if I can get a
less draconian signature for mailing list use.  In the mean time I'm
sure a few sig-less messages won't hurt anyone.
