I guess I misunderstood the purpose of automake in general.  I
understand that automake itself is portable, but is automake intended
mainly for those projects which are themselves portable?

Regarding libtool, maybe I just don't understand how libtool works.  I
can't figure out how to use libtool to generate lib*.a.  It seems
intent on restricting outputs to only lib*.la.  I eventually gave up
and started manually invoking dlltool myself to build the lib*.a from
the *.def files.  Originally, I tried supplying the *.def files to the
lib_LIBRARIES primary, but I couldn't ever figure out how to get the
.def file recognized as a valid source file (even using SUFFIXES =
.def and .def.a: $(DLLTOOL) etc ).  So basically, what it comes down
to is that I think maybe my project is too limited to blend with
automake as simply as I initially envisioned, and my knowledge of
automake is too limited to make it do what I want without asking you
tons of questions (which you have been extremely kind in answering, I
might add... though it may not seem like it, I am learning a lot from
you, so thank you for that).

Your questions about my intentions have made my intents clearer to me.
 I now know what I want to do with DLLTOOL specifically.  Tell me what
you think of this idea:

I currently use $(COMPILE) to call gcc for manually written rules.
$(COMPILE) automatically includes $(C*FLAGS) as appropriate.  I keep
thinking that $(DLLTOOL) should do likewise, but $(DLLTOOL) is more
akin to $(CC) than $(COMPILE).  What I can do is:


Then I just need to use $(MAKEDLL) in the various locations it's necessary.

What do you think?
