This chapter documents the language extensions specific to this compiler. The compiler does not recognize some of the features described in this chapter unless you specify certain compiler options on the command line. The relevant compiler options are listed in each section as appropriate.
The -features=extensions option enables you to compile nonstandard code that is commonly accepted by other C++ compilers. You can use this option when you must compile invalid code and you are not permitted to modify the code to make it valid.
This chapter describes the language extensions that the compiler supports when you use the -features=extensions options.
Note - You can easily turn each supported instance of invalid code into valid code that all compilers will accept. If you are allowed to make the code valid, you should do so instead of using this option. Using the -features=extensions option perpetuates invalid code that will be rejected by some compilers.
