Most C compilers don't like that either. The standard locution is
something like

char data[1]; /* VARIABLE LENGTH ARRAY */

where you just comment to the human reader that the array is not always
of length 1. This has some implications for sizeof() computations.
There are lots and lots of examples in the existing Postgres code.
