"gzip" is not an archiver. It is only a compressor. Traditionally, you
first "tar" files (which is an archiver) and then compress the output by
gzip. That said, there are no such files, unless you talk about .tar.gz
files - a different species, though.
gzip follows the *ix philosophy: One tool for a job. Archiving and
compressing are two (different) jobs.
So long,

Gzip members are simply concatenated. If you have two files compressed
with gzip, then just append one to the other. Upon decompression, gzip
will see the two members and concatenate the two uncompressed chunks
into a single output file.
