The diff from July, right?  I wish you'd mentioned that you'd tried
it, back after I posted it - I would have been glad to see specific
examples.  I still would, if you remember any of them.

There are at least three classes of code affected by this:

  - uses MMX, SSE, or AltiVec
  - uses unsigned char * for numerical data
  - uses unsigned char * for strings

I've spent hours searching through different bodies of code trying to
come up with comparisons here (which I posted during the last
discussion).  I believe that the first is rapidly increasingly and the
other two are about even.  I don't want to drop what I believe to be a
very useful change without at least finding some compromise.

By the way, Jan's patch (which only applies to unsigned char[] and not
unsigned char *, leaving GDB in my opinion inconsistent) is in Fedora
7.  That's relatively recent but has a lot of users; I don't see any
complaints about it in their bugzilla.
