GS/OS applications on HFS disks

[Pim Blokland <pDOTblokland@spcgroup.nl>]

I thought that when you save a file to a HFS disk, the GS does not mind
the "foreign" file system, and it just saves the file in such a way that
it is completely retrievable, including all of its attributes.

However, the other day I found that when copying a GS/OS application to
a HFS disk (with the Finder), the aux type of the app gets destroyed.
The file type remains the same ($B3), but the aux type reverts to zero.
Is this "normal"? Or is it a bug in the HFS FST? If so, is it a known
bug and is there a patch available? Of am I doing something wrong?
