_THREAD_SAFE Same as _REENTRANT, often used by other systems.
The `-ansi' switch to the GNU C compiler defines __STRICT_ANSI__.
If none of these are defined, the default is all but _GNU_SOURCE.
If more than one of these are defined, they accumulate.
If none of these are defined, the default is to have _SVID_SOURCE,
_BSD_SOURCE, and _POSIX_SOURCE set to one and _POSIX_C_SOURCE set to
199506L. If more than one of these are defined, they accumulate.
For example __STRICT_ANSI__, _POSIX_SOURCE and _POSIX_C_SOURCE
together give you ISO C, 1003.1, and 1003.2, but nothing else.
