This patch set adds the --enable-newlib-reent-binary-compat configure option
which may be used to define the new Newlib configuration option
_REENT_BACKWARD_BINARY_COMPAT.  This option is used to provide binary backward
compatibility for struct _reent by preserving unused members in struct _reent
to keep the structure layout.  Make _REENT_GLOBAL_ATEXIT the default and remove
this option.

v2:

* Rename --enable-newlib-backward-binary-compat in --enable-newlib-reent-binary-compat.

* Do not enable option for Cygwin.

* Adjust code in libgloss.

Sebastian Huber (6):
  Add --enable-newlib-reent-binary-compat
  Optional struct _reent::__unused_sdidinit
  Optional struct _reent::_unspecified_locale_info
  Optional struct _reent::_new::_unused
  Optional struct _reent::_new::_reent::_unused_rand
  Use global atexit data for all configurations
