I haven't ever used it myself, but my gzip man page says:

    ADVANCED USAGE
       Multiple compressed files can be concatenated.  In  this case,  gunzip
       will extract all members at once. For example:

             gzip -c file1  > foo.gz
             gzip -c file2 >> foo.gz

       Then

             gunzip -c foo

       is equivalent to

             cat file1 file2


(This is the man page included in the Debian gzip package, version
1.3.5-10sarge2.)
