Personally, I'd recommend using *one* -I switch and having .c files
reference extension headers with #include "extensionname/headername.h".

As I said before, I think that we should change the existing contrib
modules to be coded likewise, all using a single -I switch that points
at SRCDIR/contrib.  That'd help give people the right coding model
to follow.
