If NetBSD/cobalt (same with pmax - maybe all mipsel?) doesn't compile
$ gcc -std=c99 foo.c
(with the aforementioned alloca() call in foo.c)
...while NetBSD/i386 (and OpenBSD/i386, etc) does, then somebody has an
error. I see that you've commented on this in the past; would you call
this a bug on the other systems viz. conformance to c99?
On a related note, shouldn't this bail on compilation, and not on linking?
