I kind-of confirm this with current CVS and x01c.c.

Of course we don't expect users to do what Herng-Jeng Jou did, but users 
migh want to generate a static executable to, say, sent id to a friend?

And this raises another shared/static question: if plplot_libtool or 
pkg_config don't support both kinds of linking, we should disable 
static if shared is allowed. Or I'm missing something?
