This ought to work:
AS_IF([test x"$ac_cv_condition_for_NAME" = xyes],
[AC_DEFINE([NAME], [1], [Explanation of NAME.])],
[AC_DEFINE([NAME], [0], [Explanation of NAME.])])
And so should this:
AS_IF([test x"$ac_cv_condition_for_NAME" = xyes],
[value_NAME=1],
[value_NAME=0])
AC_DEFINE_UNQUOTED([NAME], [$value_NAME], [Explanation of NAME.])
If neither of those works, we're going to need to see a self-contained
configure.ac that demonstrates exactly what you're trying to do, because the
problem must be more complicated than just how you're using AC_DEFINE.
