Sorry, I should have said.

Maybe I've misunderstood you, but you may want to recheck the -k
documentation and/or play with it some. Your description above is
exactly what make -k avoids. For example, in the "make ethereal"
scenario we're talking about, make -k notices that packet-x11.o failed
to build, but it keeps going trying to build the other components of
ethereal that don't depend on that. However, when it comes time to
link ethereal, make knows that its dependencies haven't all succeeded,
so it says:
make: Target `ethereal' not remade because of errors.
instead of trying to link it and generating linker errors. Of course,
this assumes that the dependencies are complete, so you might actually
see something like what you describe building ethereal, since there do
seem to be some missing dependencies. But that would be a problem
with the Makefile, not make -k.

I try to maintain a healthy distance from automake/autoconf, so I have
no idea how they're supposed to interact with dependencies, but this
"feels" like it's "just" a matter of listing dependencies right in
whatever input ultimately results in Makefile, for what that's worth.
