- if >=200112L, all of IEEE 1003.1-2004
- if >=200809L, all of IEEE 1003.1-2008
- _XOPEN_SOURCE Includes POSIX and XPG things. Set to 500 if
- Single Unix conformance is wanted, to 600 for the
- sixth revision, to 700 for the seventh revision.
- _XOPEN_SOURCE_EXTENDED XPG things and X/Open Unix extensions.
- _LARGEFILE_SOURCE Some more functions for correct standard I/O.
- _LARGEFILE64_SOURCE Additional functionality from LFS for large files.
- _FILE_OFFSET_BITS=N Select default filesystem interface.
- _ATFILE_SOURCE Additional *at interfaces.
- _GNU_SOURCE All of the above, plus GNU extensions.
- _DEFAULT_SOURCE The default set of features (taking precedence over
- __STRICT_ANSI__).
-
- _FORTIFY_SOURCE Add security hardening to many library functions.
- Set to 1 or 2; 2 performs stricter checks than 1.
-
- _REENTRANT, _THREAD_SAFE
- Obsolete; equivalent to _POSIX_C_SOURCE=199506L.
-
- The `-ansi' switch to the GNU C compiler, and standards conformance
- options such as `-std=c99', define __STRICT_ANSI__. If none of
- these are defined, or if _DEFAULT_SOURCE is defined, the default is
- to have _POSIX_SOURCE set to one and _POSIX_C_SOURCE set to
- 200809L, as well as enabling miscellaneous functions from BSD and
- SVID. 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.
-
- These are defined by this file and are used by the
- header files to decide what to declare or define:
-
- __GLIBC_USE (F) Define things from feature set F. This is defined
- to 1 or 0; the subsequent macros are either defined
- or undefined, and those tests should be moved to
- __GLIBC_USE.
- __USE_ISOC11 Define ISO C11 things.
- __USE_ISOC99 Define ISO C99 things.
- __USE_ISOC95 Define ISO C90 AMD1 (C95) things.
- __USE_ISOCXX11 Define ISO C++11 things.
- __USE_POSIX Define IEEE Std 1003.1 things.
- __USE_POSIX2 Define IEEE Std 1003.2 things.
- __USE_POSIX199309 Define IEEE Std 1003.1, and .1b things.
- __USE_POSIX199506 Define IEEE Std 1003.1, .1b, .1c and .1i things.
- __USE_XOPEN Define XPG things.
- __USE_XOPEN_EXTENDED Define X/Open Unix things.
- __USE_UNIX98 Define Single Unix V2 things.
- __USE_XOPEN2K Define XPG6 things.
- __USE_XOPEN2KXSI Define XPG6 XSI things.
- __USE_XOPEN2K8 Define XPG7 things.
- __USE_XOPEN2K8XSI Define XPG7 XSI things.
- __USE_LARGEFILE Define correct standard I/O things.
- __USE_LARGEFILE64 Define LFS things with separate names.
- __USE_FILE_OFFSET64 Define 64bit interface as default.
- __USE_MISC Define things from 4.3BSD or System V Unix.
- __USE_ATFILE Define *at interfaces and AT_* constants for them.
- __USE_GNU Define GNU extensions.
- __USE_FORTIFY_LEVEL Additional security measures used, according to level.
-
- The macros `__GNU_LIBRARY__', `__GLIBC__', and `__GLIBC_MINOR__' are
- defined by this file unconditionally. `__GNU_LIBRARY__' is provided
- only for compatibility. All new code should use the other symbols
- to test for features.
-
- All macros listed above as possibly being defined by this file are
- explicitly undefined if they are not explicitly defined.
- Feature-test macros that are not defined by the user or compiler
- but are implied by the other feature-test macros defined (or by the
- lack of any definitions) are defined by the file.
-
- ISO C feature test macros depend on the definition of the macro
- when an affected header is included, not when the first system
- header is included, and so they are handled in
- <bits/libc-header-start.h>, which does not have a multiple include
- guard. Feature test macros that can be handled from the first
- system header included are handled here. */

-// the obvious thing.
-//
-// Why integral expressions, and not functions nor types?
-// Firstly, these compile-time entities are used as template-arguments
-// so function return values won't work: We need compile-time entities.
-// We're left with types and constant integral expressions.
-// Secondly, from the point of view of ease of use, type-based compile-time
-// information is -not- *that* convenient. One has to write lots of
-// overloaded functions and to hope that the compiler will select the right
-// one. As a net effect, the overall structure isn't very clear at first
-// glance.
-// Thirdly, partial ordering and overload resolution (of function templates)
-// is highly costly in terms of compiler-resource. It is a Good Thing to

- 32 -- "natural" 32-bit type (always int)
- 64 -- "natural" 64-bit type (long or long long)
- LONG32 -- 32-bit type, traditionally long
- QUAD -- 64-bit type, traditionally long long
- WORD -- natural type of __WORDSIZE bits (int or long)
- LONGWORD -- type of __WORDSIZE bits, traditionally long
-
- We distinguish WORD/LONGWORD, 32/LONG32, and 64/QUAD so that the
- conventional uses of `long' or `long long' type modifiers match the
- types we define, even when a less-adorned type would be the same size.
- This matters for (somewhat) portably writing printf/scanf formats for
- these types, where using the appropriate l or ll format modifiers can
- make the typedefs and the formats match up across all GNU platforms. If
- we used `long' when it's 64 bits where `long long' is expected, then the
- compiler would warn about the formats not matching the argument types,
- and the programmer changing them to shut up the compiler would break the
- program's portability.
-
- Here we assume what is presently the case in all the GCC configurations
- we support: long long is always 64 bits, long is always word/address size,
- and int is always 32 bits. */

- gthr-posix.h defines a symbol __GTHREAD_HAS_COND to signify that these extra
- features are supported.
-
- Types:
- __gthread_cond_t
-
- Macros:
- __GTHREAD_COND_INIT
- __GTHREAD_COND_INIT_FUNCTION
-
- Interface:
- int __gthread_cond_broadcast (__gthread_cond_t *cond);
- int __gthread_cond_wait (__gthread_cond_t *cond, __gthread_mutex_t *mutex);
- int __gthread_cond_wait_recursive (__gthread_cond_t *cond,
- __gthread_recursive_mutex_t *mutex);
-
- All functions returning int should return zero on success or the error
- number. If the operation is not supported, -1 is returned.
-
- If the following are also defined, you should
- #define __GTHREADS_CXX0X 1
- to enable the c++0x thread library.
-
- Types:
- __gthread_t
- __gthread_time_t
-
- Interface:
- int __gthread_create (__gthread_t *thread, void *(*func) (void*),
- void *args);
- int __gthread_join (__gthread_t thread, void **value_ptr);
- int __gthread_detach (__gthread_t thread);
- int __gthread_equal (__gthread_t t1, __gthread_t t2);
- __gthread_t __gthread_self (void);
- int __gthread_yield (void);
-
- int __gthread_mutex_timedlock (__gthread_mutex_t *m,
- const __gthread_time_t *abs_timeout);
- int __gthread_recursive_mutex_timedlock (__gthread_recursive_mutex_t *m,

- __SIZEOF_PTHREAD_MUTEX_T - size of pthread_mutex_t.
- __SIZEOF_PTHREAD_MUTEXATTR_T - size of pthread_mutexattr_t.
- __SIZEOF_PTHREAD_COND_T - size of pthread_cond_t.
- __SIZEOF_PTHREAD_CONDATTR_T - size of pthread_condattr_t.
- __SIZEOF_PTHREAD_RWLOCK_T - size of pthread_rwlock_t.
- __SIZEOF_PTHREAD_RWLOCKATTR_T - size of pthread_rwlockattr_t.
- __SIZEOF_PTHREAD_BARRIER_T - size of pthread_barrier_t.
- __SIZEOF_PTHREAD_BARRIERATTR_T - size of pthread_barrierattr_t.
-
- Also, the following macros must be define for internal pthread_mutex_t
- struct definitions (struct __pthread_mutex_s):
-
- __PTHREAD_COMPAT_PADDING_MID - any additional members after 'kind'
- and before '__spin' (for 64 bits) or
- '__nusers' (for 32 bits).
- __PTHREAD_COMPAT_PADDING_END - any additional members at the end of
- the internal structure.
- __PTHREAD_MUTEX_LOCK_ELISION - 1 if the architecture supports lock
- elision or 0 otherwise.
- __PTHREAD_MUTEX_NUSERS_AFTER_KIND - control where to put __nusers. The
- preferred value for new architectures
- is 0.
- __PTHREAD_MUTEX_USE_UNION - control whether internal __spins and
- __list will be place inside a union for
- linuxthreads compatibility.
- The preferred value for new architectures
- is 0.
-
- For a new port the preferred values for the required defines are:
-
- #define __PTHREAD_COMPAT_PADDING_MID
- #define __PTHREAD_COMPAT_PADDING_END
- #define __PTHREAD_MUTEX_LOCK_ELISION 0
- #define __PTHREAD_MUTEX_NUSERS_AFTER_KIND 0
- #define __PTHREAD_MUTEX_USE_UNION 0
-
- __PTHREAD_MUTEX_LOCK_ELISION can be set to 1 if the hardware plans to
- eventually support lock elision using transactional memory.
-
- The additional macro defines any constraint for the lock alignment
- inside the thread structures:
-
- __LOCK_ALIGNMENT - for internal lock/futex usage.
-
- Same idea but for the once locking primitive:
-
- __ONCE_ALIGNMENT - for pthread_once_t/once_flag definition.
-
- And finally the internal pthread_rwlock_t (struct __pthread_rwlock_arch_t)
- must be defined.

- Concurrency notes:
- The __kind of a mutex is initialized either by the static
- PTHREAD_MUTEX_INITIALIZER or by a call to pthread_mutex_init.
-
- After a mutex has been initialized, the __kind of a mutex is usually not
- changed. BUT it can be set to -1 in pthread_mutex_destroy or elision can
- be enabled. This is done concurrently in the pthread_mutex_*lock functions
- by using the macro FORCE_ELISION. This macro is only defined for
- architectures which supports lock elision.
-
- For elision, there are the flags PTHREAD_MUTEX_ELISION_NP and
- PTHREAD_MUTEX_NO_ELISION_NP which can be set in addition to the already set
- type of a mutex.
- Before a mutex is initialized, only PTHREAD_MUTEX_NO_ELISION_NP can be set
- with pthread_mutexattr_settype.
- After a mutex has been initialized, the functions pthread_mutex_*lock can
- enable elision - if the mutex-type and the machine supports it - by setting
- the flag PTHREAD_MUTEX_ELISION_NP. This is done concurrently. Afterwards
- the lock / unlock functions are using specific elision code-paths. */
