7.75 --gnu_defaults

Alters the default settings of certain other options to match the default behavior found in GCC.

Usage

When you use --gnu_defaults, the following options are enabled:
  • --allow_null_this.
  • --gnu.
  • --no_debug_macros.
  • --no_implicit_include.
  • --signed_bitfields.
  • --wchar32.
--gnu does not set these defaults. It only enables the GNU compiler extensions.
