Structure assignment has been an official part of C since around 1978.
While there MAY be some things loosely called "C compilers" that do not
support this, all the current C compilers that I know of do support it.
Since the C standard requires it for conforming implementations, there
should be no future C compilers that do not understand this.

Of course not.  What would it mean?
