I must caution against installing config.h.  You will collide with the
potential same config.h and HAVE* et al defines that the application
using your header files has figured out for itself.

It's much preferable to make sure that the installed include-files do
not depend on the autoconf'd parameters in any way.  If you really
need to use the definitions that configure has figured out for you,
it's much better, I think, to partial-evaluate so that instead of:

bar.h:

#ifdef HAVE_FOO_H
#include 
#endif

you make it unconditional (empty or just with the include).  This will
make that file machine-dependent, but you can most likely limit this
to one file and have all the other header files be shared.

And if you install config.h, it should be as PACKAGE-config.h.

It'd be nice to be able to embed little fragments of perl to do things
like that, for the "static" case that is.  But perhaps that idea has
come up before.  Or naturally the whole Makefile.am could be a
generated file if desired.

automake is supposed to generate portable Makefiles, so I think the
default should be static expansion.
