| /* Various options should be defined here, but the framework to do this |
| is not laid down so far. Especially notable are the following defines, |
| which can be used by the application to switch on or off various |
| datatypes and function prototypes: |
| |
| _BSD_SOURCE to include pure BSD functions which are not defined |
| under POSIX. |
| |
| _POSIX_SOURCE if the application requests a POSIX compatible system. |
| |
| _XOPEN_SOURCE if X/Open functions and datatypes are requested. This |
| option includes _POSIX_SOURCE. |
| |
| _GNU_SOURCE to turn on GNU extensions which might collide with defines |
| used in application or library headers. This option |
| includes _BSD_SOURCE, _XOPEN_SOURCE and _POSIX_SOURCE. |
