Strange AUX File types

[platkus@iunet (Shawn Platkus)]

I've been noticing something that I think is strange with the AUX type of some
of my files.  Mostly, I notice it with DAs INITS and ShrinkIT archives.

It seems that there is an extra bit that is getting set somehow.  I noticed
this because it screwed up some of my icons (i.e. icons didn't macth files
that I knew they should match). 

What it is is that the AUX type looks like 0000xx1x
                                                 ^----This byte is $01, why?
I notice that a lot of the files that I download off the net after I use
GSCII to convert them to a shrinkit archive have a file type of
$E0 / 8102  instead of $E0 / 8002.   I've looked in the filetype notes, but
haven't found any mention of why this bit would be set.

Anyone know why?  Also, my HardPressed CDA had an Auxtype of 0100.
I checked on the original disk from West Code, and it had this too.  So I'm not
sure if some program is setting that bit, or if it should be set that way to
signify something.  Any help would be appreciated.  It has been driving me
crazy for quite some time.

P.S.  I just packed some files with GSHK, and the type was $E0 / 8002 as 
expected.  I then encoded it with GSCII, then decoded it with GSCII, and 
now the file type was $E0 / 8102.  What gives?  Is it a bug in GSCII?  It seems
that I get this phenomenon on other files that I don't think have been 
through GSCII (like the DAs and INITS).

I'm using GSCII 2.3.1.  Is this the latest version?

Thanks
