Here's a patch.
To answer you other email: There's no warning anymore once libpci is
enabled. Only a warning when no PCI because we don't enable libpci by
default. The GPL issue is documented in the doxyfile and in configure
--help. If the user passes --enable-libpci without ever looking at what
it means, that's his fault.
