dynamic loading of the backend-code works on OS/2 via dlopen()
in principle, but there is one problem:
On OS/2 only filenames with max 8.3 length are possible for DLLs.
So loading test.dll, mustek.dll epson.dll ... works, but
agfafocus.dll or coolscan2.dll ... fails.
The patch takes the first 2 and the last 6 letters of the backend name
to form the name for the backend.dll if the backend-name is longer
than 8 letters.
The build-process on OS/2 creates
The install-process copies this file to
One has to rename this file to
to make things work
Here's the patch:
