Fixed rpm builds on viring envs ... do not unset variables unless we set

them.  Cleaned up windows code ... more compact and meaningful.  Added
comments.

# Warning - this shell script is delicate, because it is sourced by
# using . rather than simply executed. It is sourced because that is
# the only way to change the shell variables in the calling
# environment.
#
# Sourcing makes the shell script more delicate for the following reasons:
#
# * temporary variables are automatically set in the calling
# environment! WORKAROUND: we need to unset all them after using
# them to avoid polluting the calling environment;
#
# * not only the exit value of the script, but the exit value of each
# command we execute, might be interpreted by the calling
# environment. Typically, the calling environment might be using the
# shell errexit option ('set -e') in bash parlance, which causes the
# shell to exit if any command returns an error value. If this were
# a normal script, this option would mean that the shell would exit
# if the return value of the whole script were an error value; but
# because we are sourced, it is as all the commands in this script
# were executed directly in the calling environment, so *all* values
# returned by *all* commands must be non-error. [this all typically
# happens in rpm builds, where scripts are run with the errexit
# option so that errors in scripts abort the build, and now if a
# script sources GNUstep.sh, then we are exactly in this situation -
# if any command inside GNUstep.sh returns an error value (even if
# GNUstep.sh as a whole would be happy and return succes), the whole
# rpm build process aborts!]. WORKAROUND: we must make sure all
# commands return success - last resorts hacks like 'command || :'
# which always returns success whatever command returns.
#

# Set the GNUstep system root and local root
