"too big" error message under Xenix

[Richard Skrenta]

Just a simple question here.  I'm trying to get Micro Gnu Emacs to work
under 286 Xenix 2.0.4.  It compiles fine and makes a 67K executable.  When
I try to run it, however, it says "mg: too big".  I've run programs much
bigger than this, and I can't find any reference to that error message in
my manuals.  Does anyone know what "too big" refers to here?

Thanks
