Just pulled the latest svn, and have a dumb question - did you check if the 
calls

if(pNetHdr) subfile.strtbl->registerNET1(offsetNet1, pNetHdr->net1_length, 
pNetHdr->net1_addr_shift);

also need the endian fix?  net1_length is also a 32-bit...

Nope didn't check. Too much other stuff. New Suse is out. :)

Looking deeper into the code, I'm *almost* sure the attached patch is needed as to 
properly interpret "NET" sections, if support for them (whatever they are...) 
is implemented some day...

BTW, I'll be on vacation and away from may Mac's the next weeks, so I can build 
the next releases for OS X only in August.  But it's not forgotten!

Cheers, albrecht.
