      Bug#50409 Solaris 8 compatibility broken by assumption about
      printstack() being present
      
      When Bug#47391 was fixed, no assumption was made that support
      for Solaris 8 was needed. Solaris 8 lacks printstack(), and 
      the build breaks because of this.
      
      This patch adds a test for the presence of printstack() to
      configure.in for 5.0, and uses HAVE_PRINTSTACK to make
      decisions rather than the __sun define.
