The following options are available: -pedantic Issue extra warnings defined by ANSI for use of non- ANSI features. -pedantic-errors Issue errors instead of warnings that normally would be presented by -pedantic. -D_ANSI_SOURCE Tell the system header file set to use an ANSI- conformant "clean" namespace.
