Have you tried $][# (that is, using the proper m4 quoting to break the m4 macro definition into two concatenated strings) or $[]# (that is, inject an extra m4 quoted empty string)? (Which one to use depends on what level of nesting the $# appears in your macro, and whether it is likely to go through another round of m4 expansion). And if all else fails - use quadrigraphs: @S|@# -- Eric Blake [email protected] +1-801-349-2682 Libvirt virtualization library http://libvirt.org
