Hi Karl!

Thanks for the message.  Well, I believe there is nothing we can do
here.  If someone has a suggestion to make, please, step forward.
Personally, I have no idea what to do.

Hm, or maybe in such cases we can map



#error "SETVBUF_REVERSED has to be set by hand"

in config.h?

We don't care about the portability of #error here, since we are
really asking for troubles.  I like this.  No idea how implementable
it is but...

The problem is that we are addressing only half of the problem: what
if configure was making choices other than AC_DEFINE?
