Yaakov Selkowitz 84ba25226c Feature test macros overhaul: stdlib.h
Throughout, simplify the C99/C11 conditionals, and replace
__STRICT_ANSI__ with the proper internal POSIX macros.  The _*_r
reentrant functions need not be guarded (and most haven't been) because
such names in the global scope are reserved to the implementation.

atoff is unique to newlib.

dtoa is not actually exported (_dtoa_r is used internally), is
nonstandard, and the declaration conflicts with the code included in
MySQL, NSPR, and SpiderMonkey.

mktemp was removed in POSIX.1-2001.

The qsort_r declarations are reordered so that the GNU version retains
precedence.

[v]asprintf are GNU extensions, but the *iprintf, *iscanf, and

Yaakov Selkowitz 6ba26630e0 Feature test macros overhaul: sys/features.h
This is the complete rework of the feature tests macros for better
compatibility with GNU libc, primarily based on the Linux man pages
documentation:

http://man7.org/linux/man-pages/man7/feature_test_macros.7.html

The previous implementation was flawed in its approach that macros were
often used to hide symbols if defined (e.g. !defined __STRICT_ANSI__ or
!defined _POSIX_SOURCE), whereas the approach of glibc is that these macros
make symbols available when defined (e.g. defined _BSD_SOURCE, or as used
internally, #if __BSD_VISIBLE).  As much open-source software is written
with glibc in mind, this necessitated patching numerous packages just to
compile.

In particular, __STRICT_ANSI__ (which is defined by gcc -ansi or -std=c*)
was given too much importance.  This implementation limits the influence
of __STRICT_ANSI__ to controlling the default when no other feature test
macros are defined, and to the inclusion of <alloca.h> in <stdlib.h> as
documented.  These are the only places where __STRICT_ANSI__ should be
tested.

The following macros are now accepted: _ATFILE_SOURCE, _BSD_SOURCE,
_DEFAULT_SOURCE, _ISOC99_SOURCE, _ISOC11_SOURCE, _LARGEFILE_SOURCE,
_SVID_SOURCE, _XOPEN_SOURCE_EXTENDED.

The existing __*_VISIBLE internal macros have been kept mostly
compatible with the original BSD implementation, with some changes to
the criteria which controls them.  Several more macros in this style
have been added where needed for concision or accuracy.

Enabling C++11 or newer in the compiler also enables C99 and C11
functions.  Doing so should help move away from the need to define
_GNU_SOURCE in g++ for _GLIBCXX_USE_C99 support as on Linux:

Corinna Vinschen 1eb6db6efb Update setvbuf to latest OpenBSD implementation
Newlib's setvbuf function is very old and has two bugs:
- It sets the SRD/SWR flags incorrectly in case of files opened for
  reading and writing.
  See https://cygwin.com/ml/cygwin/2016-03/msg00180.html
  for a desription of the effect.
- It always sets the buffer size to BUFSIZ if it's not provided by
  the application, independent of the optimal blocksize for the
  underlying IO device.

Update setvbuf to latest code from OpenBSD to fix both problems.

Pieter du Preez 264b817b8e Define the newlib version macros in one place: _newlib_version.h.
Currently, the newlib version information needs to be updated in two places:
 - newlib/acinclude.m4
 - newlib/libc/include/sys/features.h

The goal of this patch is to:
 - supply a single location for defining the newlib version
   information: newlib/acinclude.m4
 - define __NEWLIB__, __NEWLIB_MINOR__ and __NEWLIB_PATCHLEVEL__
   This is in line with what gcc does for its version macros. See:
   https://gcc.gnu.org/onlinedocs/cpp/Common-Predefined-Macros.html

This patch moves the definition of the _NEWLIB_VERSION, __NEWLIB__
and __NEWLIB_MINOR__ macros from newlib/libc/include/sys/features.h,
to the newly generated newlib/_newlib_version.h file. Additionally,
the __NEWLIB_PATCHLEVEL__ macro was created, for completeness.

In order to stay backwards compatible, newlib/_newlib_version.h gets
included by newlib/newlib.h and newlib/libc/include/sys/features.h.

Note: This patch does _not_ include the modifications to the following
files, as these should all be generated any way.
      *Makefile.in,
      *aclocal.m4,
      *configure
      stamp-* files

Non-reentrant system calls version implies both MISSING_SYSCALL_NAMES

In case of non-reentrant system calls _sbrk_r became a macro with TWO
args (defined in reent.h):

#define _sbrk_r(__reent, __incr)  sbrk(__incr)

But in our case only one argument is present. (RCALL 0) is considered
as a single argument despite RCALL itself is a macro:)

So intermediate one-arg macro will be enough to expand args before
final _sbrk_r expansion:

#define _SBRK_R(X) _sbrk_r(X)

        target and include acle-compat.h.
        * libc/sys/arm/arm.h: Include acle-compat.h.
        (THUMB_V7_V6M): Rename to ...
        (PREFER_THUMB): This.  Use ACLE macro __ARM_ARCH_ISA_ARM instead of
        __ARM_ARCH_6M__ to decide whether to define it.
        (THUMB1_ONLY): Define for Thumb-1 only targets.
        (THUMB_V7M_V6M): Rename to ...
        (THUMB_VXM): This.  Defined based on __ARM_ARCH_ISA_ARM, excluding
        ARMv7.
        * libc/sys/arm/crt0.S: Use PREFER_THUMB rather than THUMB_V7_V6M and
        rename THUMB_V7M_V6M into THUMB_VXM.
        * libc/sys/arm/swi.h: Likewise.

Jeff Johnston c2bbc54a62 Fix atexit logic to honor _ATEXIT_DYNAMIC_ALLOC setting.
If small reent is enabled (_REENT_SMALL is defined) then malloc() was
used in __register_exitproc() even if user requested it to be disabled
(_ATEXIT_DYNAMIC_ALLOC is defined). With this fix, function fails when
_ATEXIT_DYNAMIC_ALLOC is defined and whole static storage is already
used.

        * libc/stdlib/__atexit.c (__register_exitproc): Fix for
        _ATEXIT_DYNAMIC_ALLOC.
