1/* Define how to access the int that the wait system call stores.
2 This has been compatible in all Unix systems since time immemorial,
3 but various well-meaning people have defined various different
4 words for the same old bits in the same old int (sometimes claimed
5 to be a struct). We just know it's an int and we use these macros
6 to access the bits. */

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