That won't work.

program.c:
    #include "config.h"
    #includes <libpq++.h>
<libpq++dir>/libpq++.h:
    #include "libpq++/pgconnection.h"
<libpq++dir>/libpq++/pgconnection.h:
    #include "config.h"

Lines `#include "config.h"' must include different files,
preferably in right order.
Both `-I. -I<libpq++dir>' and `-I<libpq++dir> -I.'
includes only one of `config.h's twice.
