A found close version GM.DLS redistribution file here:

https://web.archive.org/web/20141213092844/http://download.microsoft.com/download/a/9/d/a9d1c07d-541c-4b69-b136-f2a0d35e6fd6/directx_jun2006_redist.exe

I extracted it into a tmp directory, then extracted DirectX.cab friom there into a further directory, then copied gm16.dls to ~/.wine/drive_c/windows/system32/drivers/ where I renamed it gm.dls

That appears to have made the error about GM.DLS go away.
I still have to find if it fixes anything else.

Edit: It fixes neither the StylePicker Clear/Refresh problem, nor the style preview problem. No surprise there, though.

Edit: Also cannot yet select a style from StylePicker in the plugin standalone; also no surprise.
