Only in invoke.texi under the documentation of -ansi - i.e. this
particular documentation has no real reason to describe what effect other
options might have, it's documenting a particular option (-ansi) only.
The documentation in cpp.texi, and that in trouble.texi, specifically
mention "or a @option{-std} switch specifying strict conformance to some
version of ISO C". I'd say the cpp.texi documentation is the main
documentation of what a particular predefined macro means (as opposed to
the effects of a particular option on predefined macros).
