In your case I think it might be easier to build a .a file using dlltool and
a .def file. Some time ago Valery Fine (Valeri.Faine@cern.ch) posted a program
called dumpexts, based on pedump, that creates a .def file from a .dll. Run
this on ociw32.dll and then run dlltool on the resulting .def file to make
a libociw32.a. Then you should be able to build your programs using -lociw32
on your link line.

This all assumes that the library file contains only import records, not extra
statically linked functions. From the looks of it, it seems like a good bet in
this case.

I can send you the source file dumpexts.c if you wish.
