Well clearly not _every_ switch as OWC does support up to 32-bit ints in
switch expressions. At the end of the day whether or not Subversion is
compilable with OWC is a decision of their respective 'owners' and at
worst this thread highlighted both the shortfalls and a work-around for
a major one, until one or the other give a(n) 25.4 millimetres.

Have attached a patch against trunk for the suggested switch{} change
but will leave the warnings (casts,pointers,etc) to experts.

In the event something bites off the patch a copy is given below.
