Are AC_SUBST/AC_SUBST_FILE recursive? I have a case where a file inserted with AC_SUBST_FILE contains @variable@, to be substituted by AC_SUBST, but it doesn't seem to work. This is with autoconf 2.13. _But_: someone else tells me that it works for him! Ideas? Could it be that it's depending on the order in which AC_SUBST/AC_SUBST_FILE are called?
