m4_ifndef([AM_COND_IF], [AC_DEFUN([AM_CONDITIONAL], m4_defn([AM_CONDITIONAL])dnl m4_define([_AM_COND_VALUE_$1], [$2])]) BTW, I see that automake 1.11 also traces the macros _AM_COND_IF, _AM_COND_ELSE and _AM_COND_ENDIF, which are not present nor traced in 1.10, so my suggestion above might still be insufficient in some situations (if not all). My advice is: just require Automake 1.11. That's not unreasonable, since that's anyway a requirement for developers, not for users. HTH, Stefano
