it definitely isn't exposed by the SDK, because there is no import lib
iuwinapi.lib, and IIRC there never was.

see: git log -S uwinapi -p odk

the only reason Duden extension used it is that it was built wrongly,
not with the SDK but in a setsolar environment.

i find it unlikely that there are extensions other than Duden that
require uwinapi.dll... most likely only that and Sun/Oracle extensions
were built in a setsolar environment, and i'm not sure if the Oracle
extensions that weren't historically part of the OOo repo, i.e. the
proprietary ones, were ever actually released, and since ~nobody bought
the product there probably weren't any users back then, much less today.

so regarding Duden: does that work anyway today?  if it was built in
setsolar env, doesn't it require the STLPort dll as well, which we
removed years ago?
