However, I'll stress once more another lesson that you can take home. You wrote: > For years, I've been using $(ECHO) in Makefile.am's with an > AC_CHECK_PROG([ECHO], echo, echo) This is not necessary. You can just use echo, as it is a builtin and will be universally available; the only problem, which your technique doesn't solve anyway, is that it may not work when the argument contains backslashes or starts with a dash. In order to avoid rewriting your makefiles, just do AC_SUBST([ECHO], [echo]) for the time being. Paolo
