Yeah, it's in this direction, just a typo here.

There are two uses, and I've split them out in my current
patch:

 PANGO_ENABLE_BACKEND

  API needed when writing new backends needed for pangox, pangoxft,
  pangoft2, pangowin32 libraries, and also for gnome-print.

 PANGO_ENABLE_ENGINE

  Needed when writing language and shaper modules.

Neither of these can be handled with _ prefixing because _ prefixed
symbols aren't exported from the library and the symbols are
needed externally.
