When it sees "-static", Amber's configure script adds "-Bstatic" to the pgi
loader flags, and not much else. The opposite of "-Bstatic" for pgi seems
to be "-Bdynamic". I'm not clear on the distinction pgi makes between
"shared" and "dynamic", but my ignorance is not very surprising.
The short answer is that editing the config.h file as outlined above is
what is needed here, and in other cases where our configure script doesn't do
the right thing. We also welcome suggestions from users about what the
configure script *should* do, especially since I don't think many Amber
developers are using PGI.
