D'oh!  Sorry, forgot to paste it in... here's my make output tail end:
        sed 's/SUB/ci/;s/VERSION/5.8.119-8540/'  > ci
        chmod +x ci
        sed 's/SUB/co/;s/VERSION/5.8.119-8540/'  > co
        chmod +x co
        sed 's/SUB/rcs/;s/VERSION/5.8.119-8540/'  > rcs
        chmod +x rcs
        sed 's/SUB/rcsclean/;s/VERSION/5.8.119-8540/'  > rcsclean
        chmod +x rcsclean
        sed 's/SUB/rcsdiff/;s/VERSION/5.8.119-8540/'  > rcsdiff
        chmod +x rcsdiff
        sed 's/SUB/rcsmerge/;s/VERSION/5.8.119-8540/'  > rcsmerge
        chmod +x rcsmerge
        sed 's/SUB/rlog/;s/VERSION/5.8.119-8540/'  > rlog
        chmod +x rlog

Yes, and less mysterious than I first realized... I'm not even sure now
why I thought my first make after configuration was somehow different,
that's really not the case.

Comparing the gmake output shows that the sed's above are missing
their "sub.TEMPLATE" input file.  So I don't think sed itself is the
trouble, unless it's somehow involved with generating the Makefile's.

Let me know if you need any more info.
