Hmm...  There's one thing I dislike about your patch, which is that it
turns --enable-cxx-flags= into --enable-cxx-flags (with an implicit
=yes).  I'd rather set addoption to the entire string to be added to
$arguments, quoted if necessary.

Also, there are a number of other *options variables that are passed
down to sub-configures that require as much quoting as $arguments.
Those may be trickier to handle, unless you set say quotedoption and
quotedoptarg in advance, and use that whenever such variables are
appended to.
