Not a problem; the emulation is complete unto itself and has its own
ersatz System V include directory (the files in it have been tweaked
a bit to fit 4.2BSD but the user is not supposed to notice this).  I
even went so far as to avoid #including ANY native 4.2BSD headers,
but I would not recommend this as a general practice!  (I plead
extenuating circumstances.)
