I thought this was done in Wine in the spec files. Something such as:

@ stdcall ExtTextOutW(params) gdi32.ExtTextOutW

should do the trick. The function names need not to be the same.

The only limitation I have found is that you can't forward in this
way to ordinal exports but I may have missed something.
