* 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.
