Thanks Robert. A bit more reading in MSDN turned up the following:
Windows 95/98/Me: GetCharacterPlacementW is supported by the Microsoft Layer for
Unicode. To use this, you must add certain files to your application, as
outlined in Microsoft Layer for Unicode on Windows 95/98/Me Systems.

So it seems that GR_Win32Graphics::drawChars (as currently coded) requires
UnicoWS.dll on Win 95/98/ME due to its usage of GetCharacterPlacementW.
This library requirement was discussed back in May this year in relation
to the Win32 keyboard, and summarised by Dom in July this year as follows:
We hope to have AbiWord 2.2 using unicows.dll so that
we can use true unicode support for all of our input
and output on Win32. Right now, it's too close to 2.0
to even consider such a thing.

Some rework of GR_Win32Graphics::drawChars and/or XAP_Win32App::_setBidiOS
may be necesssary to call GetCharacterPlacement (without the W) on Win9x.
