As soon as I wrote the original note about the preprocessor symbols
aegis and apollo always being defined with the C compiler /bin/cc,
I realized that I should try the -U option on the cc command.    
That worked.   I now have KERMIT working on 10.1

I will report on KERMIT in another note targeted at KERMIT.
As far as cc is concerned:
     1) I dont think  /usr/include/apollo_$std.h  is being read
        automatically by /bin/cc as described by the manual.
        (I'll check it again.)
     2) The symbols   apollo   and    aegis   are predefined by
        /bin/cc (perhaps cc is wired that way but I couldnt find
        any text file other than apollo_$std.h that defines them.)
     3) The symbol   apollo   should not be undefined because many
        of the standard texts  (stdio.h, etc.) are conditional on
        "apollo" and will not compile if it isnt defined.
     4) To undefine  aegis  (which you might want to do on BSD
        for programs written to run on aegis or std BSD), you must
        have    -Uaegis   on the cc command line.

Now go see my note on KERMIT.   (Are we having fun yet.  I hope my
boss never gets to see how much time I've wasted getting all this
going!  And it was my idea to upgrade to 10.1  !  )
