Ok, I tried my luck and snooped around a bit: The problem seems to be 
within locking/posix.c ...

May 2 2000 Andrew checked in a patch surrounding map_lock_offset() 
with

   #if defined(LARGE_SMB_OFF_T)

I think this should be reversed to

   #if !defined(LARGE_SMB_OFF_T)

Roughly said LARGE_SMB_OFF_T is defined when off_t is a 64 bit value, 
so on a system without large file support LARGE_SMB_OFF_T will never 
be defined.

map_lock_offset() is a function to map 64 bit lock offsets to 31 bit 
lock offsets. There seems to be no need to do this when running on a 
64 bit system but always when running on a 32 bit system.

Andrew: Can you tell if my conclusions are correct (or naive :-)?

Joe: Could you try the attached patch on your SCO system and check if 
it works? Please note that you will have to "make proto" before 
"make" because I had to change the function header.

Regards,
        Robert
