I've fixed this part. The test is now based on 'test -ef'.

I've added a proper configure check.

This was probably the idea behind overriding the LIBS variable. But
obviously there is a problem when adding non-system libraries, such as
libz or maybe readline.

The fact is that most of the libraries that configure finds are not needed
for any given system, but that is a legacy problem for PostgreSQL and a
design flaw in Autoconf that is not worthwhile to work around unless there
is a real problem.

Bonus project: There are way too many things defined in qnx4.h. At least

#include <sys/select.h>
#define HAVE_STRING_H

should be removed. I'm also suspicious about

#include <process.h> /* for execv */

(who uses execv()?) and

#if !defined(__GNUC__)
#include <semaphore.h> /* for sem_t */
#endif

(What does this have to do with GNUC?)

Can you check that?
