The use of "#" (a null preprocessor directive) is odd.  Perfectly legal,
but odd.  I might use an ordinary comment like:

Individually declared objects can be can be initialized in place; struct
members can't.  Thinking of a collection of objects as a struct might be
useful, but IMHO it's no reason to avoid the convenience of
in-place initialization.

It's not an extension; it's a standard language feature, starting with
C99, called "compound literals".

    local_variables = (struct foo){1, 0, 1, 0};

(Note that "(struct foo)" is not a cast; it's part of the syntax of the
compound literal.)

Of course if you insist on sticking to C90 you don't get to use things
like this.
