NetBSD's appears to be the same as 4.4 lite 2. I was curious as : > to why the difference between the two existed. The CVS tree is : > unenlightening when I asked it for a revision history. : : Hmmm.... I don't mean to point out what may be the obvious, but isn't : EOF == -1? Yes. However, the NetBSD doc specifically says that getopt returns -1 and the FreeBSD doc says EOF. While they are both the same in this implementaiton, pedantically, FreeBSD should use -1. This change won't break anything, since EOF does == -1 (assuming that other lite2 deltas don't impact this). Warner
