Does anybody have an idea of *how* to actually do that?

My first thought was to just generate a DEF file whenever any of the
object files have changed, which could be a simple date comparison.
However, generating the DEF file is *really* expensive and slow, so
this would make rebuilding anything that *doesn't* add or remove an
entrypoint unacceptably slow..

Can someone think of a way to do this without having to dump the list
of exports from each and every object file?
