I agree that the fact that the coreutils people broke gcc builds was a
mistake; even if we decide to change, we can't retroactively fix gcc
builds that we have already released. But which systems don't support
head -n1 and tail -n1? I've scouted about 8 OS flavors I have access to
(Solaris, HP-UX, SGI-MIPS, Alpha OSF, FreeBSD, Linux, AIX) and they all
handle it. SunOS4, perhaps?
