Please note that using the fat directory structure will not blend

# Is the system multi-platform?
#--------------------------------------------------------------------
#
# Multi-platform means that GNUstep.sh will determine the host
# platform (by running config.guess) each time that it is sourced.
# This is good if you are sharing your GNUstep.sh across your network
# (for example, mounting the makefiles via NFS), but it requires you
# to be able to run config.guess on your machine(s), which usually
# requires a development environment (compiler, libc etc).
#
# The default instead is not using multi-platform, which means the
# local host os, cpu and version is hardcoded in GNUstep.sh. This
# works nicely for a single machine using this gnustep-make
# installation, and it works even if you don't have development
# packages (gcc, binutils, libc-dev etc) installed. We had to make
# this the default after end-users (with no development packages
# installed) complained that binary packages wouldn't work (and the
# reason turned out to be that GNUstep.sh was running config.guess
# which was returning the wrong platform because the development
# tools needed/used to determine the platform were not available).
#
# Unless you know what you are doing, stick with the default, which is
# also much faster when sourcing GNUstep.sh.
