[bug] gzip -l file size

[m8535]

Dear Sir,

  First, I want to thank you for your great job. :)

However, I found "gzip -l" can't correctly provide
the compressed and uncompressed file size.

For example, if a file has
an uncompressed file size: 48172948600 (2^32 * 11 + 928308344) with
a compressed file size: 7005169525 (2^32 * 2 - 1584765067),
the result of "gzip -l" is:
compressed  uncompr. ratio uncompressed_name
-1584765067 928308344 -191.9% 18.d

Therefore, I think this bug may be resolved by "long long int"
variables in C, instead of "long int" variables.

Here is the outcome of "gzip -V":
gzip 1.2.4 (18 Aug 93)
Compilation options:
DIRENT UTIME STDC_HEADERS HAVE_UNISTD_H ASMV
