This option is used to provide binary bac= kward compatibility for struct _reent by preserving unused members in struct _r= eent 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.
