there should be a "dependency" (in the Makefile) of executables upon
libraries that should force re-linking. For instance, now in PW/Makefile
there is a line like

pw.x : $(PWOBJS) libpw.a

I guess this should be something like

pw.x : $(PWOBJS) libpw.a $(LIBOBJS)

Disclaimer: I am no expert in Makefiles and never really understood  
how it works.
My knowledge of Makefiles comes from experiment rather than from  
theory. I
tend to keep the Makefiles as simple as possible, because several  
times I noticed
that adding more dependencies has unintended consequences (i.e.  
unnecessary
  recompilation or linking)

I don't think this is useful: "makedeps.sh" finds dependencies via  
f90 modules,
or via #include directives. There are no such dependencies in flib/;  
those in clib/
are already accounted for

Sorry for today's deluge of messages: for some obscure reasons,
the mailing list software keeps disabling my subscription (and only
mine, apparently), so several messages were pending, waiting
for (my) approval since two weeks.
