Thanks. But then, I would suggest that this is misleading: the sections "Options Controlling C Dialect » and "Options Controlling C++ Dialect" are not as symmetrical as their names would imply. Maybe the C++ section could at least have an item about -std that points to the C documentation. Yes, that would make sense. >> Also >> https://gcc.gnu.org/projects/cxx1y.html >> https://gcc.gnu.org/projects/cxx1z.html >> >> >>> https://gcc.gnu.org/onlinedocs/gcc/Standards.html#index-std-60 > > My point here was that this page documents C++ up to C++11, and points to "Options Controlling C++ Dialect" for more information about C++ standards, whereas you just showed that it’s the page about C dialects that should be pointed to, and that there are many more options that what this section reports. I'll update that section to refer to later C++ standards, I'd forgotten it existed. >>> >>> Finally, one would expect to see documentation about -std in "Options Controlling C++ Dialect", since the corresponding about C documents -std for C. >>> >>> https://gcc.gnu.org/onlinedocs/gcc/C_002b_002b-Dialect-Options.html#C_002b_002b-Dialect-Options >> >> That's the documentation about -std in general, not -std for C.

Maybe -std deserves a section on its own. I guess that gccgo, gnat and other also use this -std option, so even if the main documentation for GCC does not cover these languages, it would make sense to detach it from C. Say next to -x. I think only the C-family of languages use that option.
