I may not have clarified -there are 2 versions of the library.
(1) win CE library that runs on X/scale
(2) Visual C++ library that runs on Windows XP.

# objcopy -I windows_filename -O netbsd_filename
will automatically make it a netbsd usable library?

This seems to be a work in progress.

Not a v. cooperative/competent vendor.
