  	* tests/cond11.test: Use `=', not `=='.
  	* tests/cond12.test: Look for automake in build directory, not
  	source directory.
  
  2001-06-29  Richard Boulton  <richard@tartarus.org>
  
  	* automake.in (conditionals_true_when): Pass first parameters by
  	reference, avoiding bug which put all parameters in @CONDS instead
  	of @WHENS.  Report by Kalle Olavi Niemitalo.
  	Take a single WHEN instead of an array of WHENS.
  	Remove FIXME; can't now have an empty @WHENS.
  	(conditional_is_redundant): New sub.
  	(variable_conditions_reduce): Check whether each condition is
  	implied by any of the other conditions (other those already
  	discarded), rather than checking only against those already
  	considered (and kept).  Also, fix sense of check: was keeping
  	tautologous terms instead of discarding them.  Use
  	conditional_is_redundant instead of conditionals_true_when.
  	* tests/Makefile.am (TESTS): Added cond11.test and cond12.test.
  	* tests/cond11.test: New file.
  	* tests/cond12.test: New file.
