_GNU_SOURCE All of the above, plus GNU extensions.
The `-ansi' switch to the GNU C compiler defines __STRICT_ANSI__.
- If none of these are defined, the default is _GNU_SOURCE.
+ If none of these are defined, the default is all but _GNU_SOURCE.
If more than one of these are defined, they accumulate.
For example __STRICT_ANSI__, _POSIX_SOURCE and _POSIX_C_SOURCE
together give you ANSI C, 1003.1, and 1003.2, but nothing else.
