All these are in fact handled fine by binary diffs, so I've removed these and a fair number of others that have small binary diffs from the testsuite. > I have modified gzip to dump the skipped extra fields.

(Googling for > gzsig makes it appear wide-spread on *BSD.) Ah, I was not aware of gzsig. Makes sense. Regarding modification times, compression levels, FNAME, and OS types, these are all handled by pristine-gz; it records that info and passes it to zgz when recreating the gz file. > Most notably, 0x03 (Unix) is missing; no original file was > compressed on such an OS. Yeah, I suspect that many of the problem files were built using gzip clones or highly modified versions on non-unix operating systems. -- see shy jo
