-/* Unexec for Xenix.
-   Note that the GNU project considers support for Xenix operation
-   a peripheral activity which should not be allowed to divert effort
-   from development of the GNU system.  Changes in this code will be
-   installed when Xenix users send them in, but aside from that
-   we don't plan to think about it, or about whether other Emacs
-   maintenance might break it.

-  On 80386 Xenix, segmentation screws prevent us from modifying the text
-  segment at all.  We basically just plug a new value for "data segment
-  size" into the countless headers and copy the other records straight
-  through.  The data segment is ORG'ed at the xs_rbase value of the data
-  segment's xseg record (always @ 0x1880000, thanks to the "sophisticated
-  memory management hardware" of the chip) and extends to sbrk(0), exactly.
-  This code is afraid to malloc (should it be?), and alloca has to be the
-  wimpy, malloc-based version; consequently, data is usually copied in
-  smallish chunks.
