In C, no; in gcc, yes.
NetBSD uses gcc. If you expect to build NetBSD code with any other
compiler, you may have work to do; this is a simple example. (I've
seen nods made in the direction of compatability with other compilers,
but they are usually restricted to userland utilities; stuff like
<sys/syscallargs.h> that are used only by the kernel get less attention
in that direction.)

I'm not sure why this is relevant; attempting to build NetBSD source
code (I note .../netbsd/... in the pathname above, and you asked this
on (among others) a NetBSD mailing list) with a FreeBSD Makefile is
bound to be an "on your own" sort of thing.

You will have to either rework it to avoid the zero-size array or
switch to using a compiler that supports a C-like language including
zero-size arrays (such as gcc).
