#
# SYNOPSIS
#
# AX_SUBST_WITH([varname])
#
# DESCRIPTION
#
# a very simple macro but also very helpful - the varname is usually the
# one from an AC_ARG_ENABLE or AC_ARG_WITH option. it is transliterated
# into uppercase and a prefix WITH_ and WITHOUT_ that are both _SUBSTed.
#
# Only one of these is set to "#" while the other is empty. In other words
# a call like AC_WITHNONE(enable-call) will create two SUBST-symbols as
# WITH_ENABLE_CALL and WITHOUT_ENABLE_CALL. When the varname had been set
# to something not "no" or "0" or ":" or "false" then it results in
#
# WITH_ENABLE_CALL="" ; WITHOUT_ENABLE_CALL="#"
#
# which you can use in your Makefile quite easily as if using an
# AM_CONDITIONAL but which can be also parsed by normal make
#
# USE = @WITH_ENABLE_CALL@ -Denabled USE = @WITHOUT_ENABLE_CALL@
# -Dnot_enabled
