I hope I won't forget to fix this in the next ABI break... It's been in
my huge queue for far too long.

I think it is. Arguably all 'unsigned int' in here should be DES_LONG,
but there are too many, so too much churn and for the others this
wouldn't actually change anything.

ok

While it caught many actual bugs and rightfully suggested that some
software visit the attic, I don't think there's UB involved in the code
as it is without patch (no coffee yet, though). This new error sure is a
bit on the picky side...
