This option alters the default settings of certain other options to match the default behavior found in GCC. Platform-specific settings, such as those targeting ARM Linux, are unaffected.
Usage--gnu_defaults does not imply specific
targeting of ARM Linux.
When you use --gnu_defaults, the following
options are enabled:
--allow_null_this--gnu--no_debug_macros--no_hide_all--no_implicit_include--signed_bitfields--wchar32.
--gnu does not set these defaults. It only
enables the GNU compiler extensions.
When you use --arm_linux and other ARM
Linux-targeting options, --gnu_defaults is automatically
implied.
