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
