# to some nonsence/non-working place like under /usr/local/etc/
#
# NOTE: this changes expected configure behavior: if you specify --prefix
#        it will not change sysconfdir, instead now one have to specify
#        --sysconfdir explicitly. To make it more clear we print
#        current sysconfdir value at the end of configure run.

# FIXME: dirty hack, may not work with some autoconf versions.
