Re: [PATCH] Handle volatile array types in dwarf2read.c.

It's fine to leave it.

Wow, I wonder how long I've had the incorrect view of make_cv_type.
Hopefully not too long.  Thanks for pointing that out.

Well, I was thinking this:

    typedef int atype[23];
    const atype a;

However, gcc omits the typedef from the DWARF, so I suppose some
hand-crafted DWARF would have to be written.


This patch is ok.  If there's a further bug and you want to fix it, it's
fine to do that separately.
