Advice in C code

[V. <gae...@no...>]

    Hello all,

    I've been working a bit on the povray terminal (I am very slow
but it has finally made some progress).

    I have a question to which I have not been able to find local advice
on :

    Is the syntax :

    current_color =3D (rgb_color){0, 0, 0};

    Standard and portable. It compiles with gcc 3.3.5 but I do not know
if it is standard C.

    Thank you
