The problem is in ..../source/script/mkproto.sh within the line:

proto_src="`echo $@ | tr ' ' '\n' | sed -e 's/\.o/\.c/g' | sort | uniq | egrep -v 'ubiqx/|wrapped|modules/getdate'`"
                      ^^^^^^^^^^^

In the tr call, QNX's shell is substituting space with literal 'n' rather
than carriage returns.  So, rather than being divided up into single
lines with one file.c on each line, they're all crammed together onto a
single line, separated uselessly by 'n's.  :-(.  I'm not a shell expert,
but NOTHING I tried could persuade QNX's shell to interpret '\n' as
carriage return.  Trying a sed in place of the tr didn't help either.

As a workaround, I put in an AWK script instead.  (OK, this is overkill,
but it seemed to work.)  In fact, I took out the sed command too, so it
didn't look _too_ abtuse.  Here is what "seemed to work" for me:

proto_src="`echo $@ | gawk '{for (i = 1 ; i <= NF ; i += 1) {gsub (/\.o/, ".c", $i); print $i}}' | sort | uniq |  
                      ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
rep -v 'ubiqx/|wrapped|modules/getdate'`"

(Apologies for any line-break problems in the above.  I'm using MS
Outlook.  :-()

When I say "seemed to work", I mean that the build hung up later on on
something else.  :-(  I'll get there!
