+ material.
+
+ - Macro: _XOPEN_SOURCE
+ If you define these macro, functionality described in the X/Open
+ Portability Guide is included. This is an superset of the POSIX.1
+ and POSIX.2 functionality and in fact `_POSIX_SOURCE' and
+ `_POSIX_C_SOURCE' get automatically be defined.
+
+ But as the great unifaction of all Unices there is also
+ functionality only available in BSD and SVID is included.
+
+ If the macro `_XOPEN_SOURCE_EXTENDED' is also defined, even more
+ functionality is available. The extra functions will make all
+ functions available which are necessary for the X/Open Unix brand.
- Macro: _GNU_SOURCE
If you define this macro, everything is included: ANSI C, POSIX.1,
- POSIX.2, BSD, SVID, and GNU extensions. In the cases where POSIX.1
- conflicts with BSD, the POSIX definitions take precedence.

+ POSIX.1 conflicts with BSD, the POSIX definitions take precedence.
If you want to get the full effect of `_GNU_SOURCE' but make the
BSD definitions take precedence over the POSIX definitions, use
compiler or linker. *Note:* If you forget to do this, you may get
very strange errors at run time.
+ - Macro: _REENTRANT,_THREAD_SAFE
+ If you define one this macro, reentrant versions of several
+ functions get declared. Some of the functions are specified in
+ POSIX.1c but many others are only available on a few other systems
+ or are unique to GNU libc. The problem is that the
+ standardization of the thread safe C library interface still is
+ behind.
+
+ Unlike on some other systems no special version of the C library
+ must be used for linking. There is only one version but while
+ compiling this it must have been specified to compile as thread
+ safe.

We recommend you use `_GNU_SOURCE' in new programs. If you don't
specify the `-ansi' option to GCC and don't define any of these macros
-explicitly, the effect is the same as defining `_GNU_SOURCE'.

When you define a feature test macro to request a larger class of
features, it is harmless to define in addition a feature test macro for
