* JOBS -> 1 if you have Berkeley job control, 0 otherwise.

* SYMLINKS -> 1 if your system includes symbolic links, 0 otherwise.
|
|
* DIRENT -> 1 if your system has the SVR3 directory(3X) routines.

|
* UDIR -> 1 if you want the shell to simulate the /u directory.

|
* USEGETPW -> 1 if getpwnam() must be used to look up a name.
|
|
* ATTY -> 1 to include code for atty(1).
|
