Bug report

[Jochen Quick]

I'm running awk on Suse Linux 9.3. Is this a bug or a feature? /[D-W]/
should be case sensitive and not include 'e', 'w' and everything in between.
But if it is case insensitive, why isn't 'd' included then? Same goes for
uppercase characters in lower case ranges. In case it is a bug, short
cofirmation would be appreciated.
