  Modified files:
    gnu/usr.bin/gzip     gzip.h 
  Log:
  Gzip assumes 'unsigned long' is 32-bits wide and depends on this.
  One thing Gzip does is implicitly by store the size of a file into an
  'unsigned long' rather than  explicitly compute the remainder modulo 2^32
  (see RFC 1952 section 2.3.1 "ISIZE").  Thus an extracted file size is
  does not equal the original size (mod 2^32) for files larger than 4GB.
  
  This manifests itself in errors such as:
          zcat: bigfile.gz: invalid compressed data--length error
