/* Define an ELF note identifying the operating-system ABI that the
executable was created for. The ELF note information identifies a
particular OS or coordinated development effort within which the
ELF header's e_machine value plus (for dynamically linked programs)
the PT_INTERP dynamic linker name and DT_NEEDED shared library
names fully identify the runtime environment required by an
executable.
The general format of ELF notes is as follows.
Offsets and lengths are bytes or (parenthetical references) to the
values in other fields.
offset length contents
0 4 length of name
4 4 length of data
8 4 note type
12 (0) vendor name
- null-terminated ASCII string, padded to 4-byte alignment
12+(0) (4) note data,
The GNU project and cooperating development efforts (including the
Linux community) use note type 1 and a vendor name string of "GNU"
for a note descriptor that indicates ABI requirements. The note data
is four 32-bit words. The first of these is an operating system
number (0=Linux, 1=Hurd, 2=Solaris, ...) and the remaining three
identify the earliest release of that OS that supports this ABI.

#ifndef _FEATURES_H
#define _FEATURES_H 1
/* These are defined by the user (or the compiler)
to specify the desired environment:
__STRICT_ANSI__ ISO Standard C.
_ISOC99_SOURCE Extensions to ISO C89 from ISO C99.
_ISOC11_SOURCE Extensions to ISO C99 from ISO C11.

__STDC_WANT_IEC_60559_TYPES_EXT__
Extensions to ISO C11 from TS 18661-3:2015.
_POSIX_SOURCE IEEE Std 1003.1.
_POSIX_C_SOURCE If ==1, like _POSIX_SOURCE; if >=2 add IEEE Std 1003.2;
if >=199309L, add IEEE Std 1003.1b-1993;
if >=199506L, add IEEE Std 1003.1c-1995;
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 machine-dependent file <bits/typesizes.h> defines __*_T_TYPE
macros for each of the OS types we define below. The definitions
of those macros must use the following macros for underlying types.
We define __S<SIZE>_TYPE and __U<SIZE>_TYPE for the signed and unsigned
variants of each of the following integer types on this machine.
16 -- "natural" 16-bit type (always short)
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, always 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. */
