  Modified files:
    lib/libz             zconf.h 
  Log:
  Hard-configure z_off_t as long.  Soft configuration using HAVE_UNISTD_H
  just breaks the prototypes for gzseek() and gztell() when an application
  defines HAVE_UNISTD_H before including <zlib.h>.  z_off_t was always
  long for compiling zlib, but was sometimes off_t for compiling
  applications, e.g., Ethereal 0.7.5.
  
  This "fix" preserves bug for bug binary compatibility.  z_off_t should
  be off_t for everything, but zlib doesn't support off_t being longer
  than long, so using the correct type without fixing zlib's internals
  would at best break binary compatibility.  This "fix" also make the
  namespace problems for HAVE_UNISTD_H no worse than hundreds of other
  namespace prooblems in zconf.h.  I'll wait for a new release of zlib
  for proper fixes.
