While I'm the first one to throw stones at SCO-ODT this needs to be
clarified.  The problem is not a deficiency in SCO the utilities, but
rather a very complicated /usr/include/sys/signal.h with preprocessor
conditionals that end up defeating the scripts assumptions.  If the
problem was with the utilities using gnu substitutes should fix it and
they don't.

BTW - attached is the hacked version of SCO's sys/signal.h that I use to
build a good rc.
