gzip 1.3.12 does not preserve file modification times on Windows

[Ryan Malayter]

It appears that neither the .gz archive file nor a decompression of that file 
preserves the file modification time on Windows (Vista Sp2)

See test below, note the original file modification time:

C:\temp>dir yslow1.htm
 Volume in drive C is OS
 Volume Serial Number is 0ECE-540D

 Directory of C:\temp

07/19/2009  12:22 PM           251,907 yslow1.htm
               1 File(s)        251,907 bytes
               0 Dir(s)  47,129,296,896 bytes free

C:\temp>gzip yslow1.htm

C:\temp>dir yslow1.htm.gz
 Volume in drive C is OS
 Volume Serial Number is 0ECE-540D

               0 Dir(s)  47,129,530,368 bytes free
