There is currently a big debate going on in the gcc-patches mailing list
(for example, http://gcc.gnu.org/ml/gcc-patches/2005-11/msg00621.html)
about whether "tail +16c" is allowed to have backwards-compatible
behavior, or whether it is a coreutils-5.93 bug that it behaves as "tail
./+16c" when _POSIX2_VERSION=200112. NEWS documents that "tail -4" is
once again supported, but that "tail +4" is still problematic. On the
other hand, the meeting minutes from austin at
http://www.opengroup.org/austin/docs/austin_239.html mention that the
intent is to 'add to the OPTIONS "except that '+' may be recognized as an
option delimiter as well as '-'.' So maybe it is worth patching tail in a
5.94 release to treat "tail +16c" the way the gcc build process claims it
should be. But I don't want to chime in on the gcc-patches list until we
have some consensus as to what the correct response to their complaints
should be.
