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 am not using the Makefile of FreeBsd 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. > and trying to write my own make file which will work for this code. 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). der Mouse mouse@rodents.montreal.qc.ca 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
