/* Define how to access the int that the wait system call stores.

|
This has been compatible in all Unix systems since time immemorial,
|
|
but various well-meaning people have defined various different
|
|
words for the same old bits in the same old int (sometimes claimed
|
|
to be a struct). We just know it's an int and we use these macros
|
|
to access the bits. */

/* The following macros are defined equivalently to their definitions
|
|
in POSIX.1. We fail to define WNOHANG and WUNTRACED, which POSIX.1
|
|
<sys/wait.h> defines, since our code does not use waitpid(). We
|
|
also fail to declare wait() and waitpid(). */
