Using /Qipo

[Dishaw__Jim]

I have a project that consists of several libraries that are used to create a DLL, which is then linked to a driver program.
I have discovered if you specify the /Qipo option (or /Qipo-c) with a library, you get a essentially an empty library because all the symbols are unreferenced.
When should /Qipo be specified? Do the libraries need DEC$ lines to indicate that a subroutine is an entry point that will be externally referenced?

As far as I know, it's fine to specify /Qipo when building a library but you must also specify /Qipo when linking the DLL. The library does not contain normal object code.
