>Description:
	Various gzip (probably libz) operations fail when dealing with more than
4GB of uncompressed data.  For instance, if you try extracting a gzipped
file that is 4097 MB when uncompressed, you always get a:
gzip: invalid compressed data--length error
even though it actually uncompresses just fine.

gzip -l and gzip -t fail in similar ways.

>How-To-Repeat:
	dd if=/dev/zero bs=1m count=4097 | gzip -c > test.gz
	gzip -l test.gz  # Notice the uncompressed size is 1MB, ratio is negative
	gzip -c -d test.gz | wc -c   # Notice the error, but 4097MB were extracted

>Fix:
	Probably bump the size of some variable somewhere.
