If you don't use the gzip option "-n", both the name and timestamp of the
original file is encoded into the gzip archive.  This encoding makes the
compressed versions different from one build to the next.

Uncompressing resolves this since the file contents themselves are correct.

As for why they are being left uncompressed, when I could just re-gzip them
using the -n option..  My expectation is I'm going to be adding a new
package.bbclass step that searches for specific documentation files (man pages
specifically) and compresses them with the correct option(s) to avoid this
conflict.  So leaving them uncompressed made the most sense to me.

(Note, almost all of the other generated man pages on the system are already
uncompressed... that was the secondary reason for the change.)

Yes, this should have been with the previous patch dealing with header conflicts.
