Thanks.  Maybe it's just me, but I'd consider that to be bug in sbrk()...
the limit is already maxed.  Yes, this program doesn't specifically need
that method and could use _djgpp_nearptr_enable.  However, I think a couple
other programs I've got may need that method.  I recall there was some
reason I didn't want to change cs.  I looked over the _djgpp_nearptr_enable
code previously but didn't see anything that indicated information was
passed to other routines.  I'll look over it again, and sbrk() and the crt0
stuff...
