[Bug bootstrap/24984] New: Use of old "tail" parameters in Makefile*

[malitzke at metronets dot com]

The "tail" utility in its newer versions requires 'tail -c +16' instead of the
previous 'tail +16c'.
This older version seems to used from gcc-3.4* through gcc-4.1* Makefile.in. It
affects testing against stage2.
a simple test that shows this is to execute from the gcc-package root the
following:
for i in `find -name 'Makefile*'` ; do grep -H -e 'tail +16' $i ; done
This is pretty petty stuff but cqan save some annoyance.

As mentioned over and over again, coreutils is wrong.

See PR 14251 and some new discussions on this recently.

------- Comment #2 from malitzke at metronets dot com  2005-11-22 06:00 -------
Upon further investigation using coreutils-5.93 (using both the documentation
and the compiled tail as test case) the following stands out:
The interpretation adopted by support is on valid if env _POSIX2_VERSION=199209
is set. The default used by the coreutils group is valid if 
env _POSIX2_VERSION=200112 is set.
If the GCC group has valid reason to insist on the older (1992) POSIX standard
the the __solution__ to this issue might be to have a statement in the main
configure file like: env _POSIX2_VERSION=199209 preceded by a comment like:
# As all other GCC applicable standards refer to the period befor December 2001
we are also using the POSIX2 standard of 1992 for our use of head or tail.
Claiming the coreutils group to be wrong will not solve the problem for the
users of GCC.

Please read the recent thread:
http://gcc.gnu.org/ml/gcc-patches/2005-11/msg00618.html

Especially this one:
http://gcc.gnu.org/ml/gcc-patches/2005-11/msg00783.html

Again coreutils is buggy.
