/*
* environ.c - define the variable environ
*/
/* $Header$ */
/*
* This file defines the variable environ and initializes it with a magic
* value. The C run-time start-off routine tests whether the variable
* environ is initialized with this value. If it is not, it is assumed
* that it is defined by the user. Only two bytes are tested, since we
* don't know the endian-ness and alignment restrictions of the machine.
* This means that the low-order two-bytes should be equal to the
* high-order two-bytes on machines with four-byte pointers. In fact, all
* the bytes in the pointer are the same, just in case.
