Another bug in the xenix large model version of compress...
This shows up on uncompressing so your compressed files are
probably ok (unless there are other bugs lurking).  Symptoms
are mangled files after zcat'ing or uncompress'ing.  This
patch assumes you have applied the sco-compress diffs and
really only changes the macro de_stack.  I also have the recent
bugfix installed to not unlink when zcat'ing so the patch will
probably fail if you don't.  The relevent line is #define de_stack
if you have trouble with patch.
