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 
#define HAVE_STRING_H

should be removed.  I'm also suspicious about

#include                     /* for execv */

(who uses execv()?) and

#if !defined(__GNUC__)
#include                   /* for sem_t */
#endif

(What does this have to do with GNUC?)

Can you check that?
