# ===============================================================================
#
# SYNOPSIS
#
# AX_SET_DEFAULT_PATHS_SYSTEM
#
# DESCRIPTION
#
# the most interesting changes go about windows-targets - where the
# default_prefix is set to /programs, and quite some directories are
# aliased: sbindir := libdir := bindir and the docprefix-defaults are also
# a bit different, even on FHS2-compliant systems where the mandir is
# going to $prefix/man only if prefix=/usr, otherwise they shall go to
# $datadir/man. We use an extra docprefix to express it which is either
# defined as being prefix or datadir. not SUBSTed here.
