It is perfectly legal, and therefore portable to all C implementations.
There may, however, be programs that purport to be C compilers that don't
implement it, although I don't know of any.

(The real test, of course, is whether

	cmdchr = menu_selection["rofq"];

yields the same result.  Any compiler that doesn't produce object code that
yields the same result isn't a C compiler.)
