  17 dnl Configuing QT is a pain in the neck if you want to support all
  18 dnl versions, as the layout of the API has changed significantly
  19 dnl between Qt3 and Qt4. In Qt4, all the top level includes are in a
  20 dnl 'Qt' subdirectory now. Since it's best for now to handle the path
  21 dnl changes in the source files so we're concious of the changes, we
  22 dnl set version flags in config.h and use Automake conditionals to
  23 dnl force one behaviour or the other.
