With coreutils 5.92, you don't need _POSIX2_VERSION=199209 in your
environment to use "head -5".  "head -5" now has the traditional
meaning regardless of _POSIX2_VERSION's value.  This change came about
becase of clarifications to the standard issued January 2005 by the
Austin Group.  Please see the NEWS file for details.

You may still need to set _POSIX2_VERSION=199209 if you are running
older coreutils versions.

It's not a bug.  This sounds like a mere style issue.  C has
well-defined behavior here, and that code operates correctly as far as
I can see.
