# Compilation with glibc version later than 2.3.2 needs the environment
# variable DEFAULT_POSIX2_VERSION set to 199209.
# Without the next line, the coreutils will start complaining about 'obsolete'
# command switches, like "tail -20" will be considered obsolete.
# This behaviour breaks many other packages... the 'obsolete' parameters are
# too commonly used to disregard them.  Better to stick with the older more
# widely accepted standards until things begin to demand the new way.

# We have had the mktemp from debianutils included with Slackware for quite a

# break existing scripts, unless someone can tell me a good reason why we
# should start using a new version of mktemp, we will continue to use the
# one we've been using.  If the new one starts to become expected, let me know.
