I don't think that works currently. Libtool sets $ECHO early in configure and uses that when writing config.status. When users overwrite that, it may break the generated libtool script on some systems. Add to that that Libtool used to AC_SUBST([ECHO]). I guess Libtool needs to be fixed to either not use ECHO, MV, and RM any more in its configure macros, or claim ownership of these names. They overlap with what other packages use and/or set. One complication is that $ECHO is used in some other libtool substitutions ($archive_cmds etc) as well, which means that, when we rename to, say, $lt_ECHO, some configure script trying to use $archive_cmds *at configure time* (after LT_OUTPUT) will then break. :-/ For $RM there has been a report recently, with another package using AC_SUBST([RM], [rm]) and Libtool expecting RM="rm -f" all over the place. Whatever we do, NEWS needs a big warning note. Cheers, Ralf
