Re: dtc: Fix recognition of whitespace characters

So, like, the other day David Gibson mumbled:

At present, the lexer in dtc recognizes only space, tab and newline as
whitespace characters.  This is broken; in particular this means that
dtc will get syntax errors on files with DOS-style (CR-LF) newlines.

Doctor, it hurts when I use DOS. :-)

This patch fixes the problem, using flex's built-int [:space:]
character class.
