I said SunOS 4.0, not SunOS 4.0 on a Sun 4/110 or SunOS 4.0 on a Sun
3/50.  To distribute any binary with my product would require me to
ship two copies, three if I need to handle a Sun 386 someday.

Since we make a Sun4-compatible system, shipping a Sun 4 version
would be fairly easily (of course, I would have to stick my copy
of GNU awk down in /usr/lib/<myprojectdirectory>), but that doesn't
work for the other systems.

No, I said it was for a specific OS.  What I meant was that if I have
control over all of the machines (specific machines, not class of
machines), I can be sure to have everything I need.

Finally, "just distribute it" is not always a reasonable answer.  For
the Department of Chemical Engineering, it may be a simple choice.
For Solbourne Computer, Inc., it's not that simple.  Distributing
more software, especially in an age where there are still computer
systems that have disks not quite big enough to handle a full Unix
and still have adequate user space, takes some thought and action.

Just because something is free doesn't mean it's easy to add to a
product.
